Transition metal?catalyzed arene functionalization has been widely used for molecular synthesis over the past century. In this arena, copper catalysis has long been considered a privileged platform due to the propensity of high-valent copper to undergo reductive elimination with a wide variety of coupling fragments. However, the sluggish nature of oxidative addition has limited copper?s capacity to broadly facilitate haloarene coupling protocols. Here, we demonstrate that this copper oxidative addition problem can be overcome with an aryl radical?capture mechanism, wherein the aryl radical is generated through a silyl radical halogen abstraction. This strategy was applied to a general trifluoromethylation of aryl bromides through dual copper-photoredox catalysis. Mechanistic studies support the formation of an open-shell aryl species.

A family of 6-hydroxypicolinamide ligands have been identified as effective supporting ligands for Cu-catalyzed couplings of heteroaryl bromides and chlorides with heteroaryl primary amines. The C-N couplings are carried out at 80-120 C in DMSO or sulfolane using K2CO3 or K3PO4 as the base with 2-10 mol % CuI and supporting ligand. The strength of the base was found to have an impact on the chemoselectivity and rate. The use of K2CO3 as the base enabled selective C-N coupling of aryl bromides over aryl chlorides with 2-5 mol % Cu at 80-120 C. With K3PO4 as the base, aryl chlorides are capable of undergoing C-N coupling, though 5-10 mol % Cu is required at 120-130 C. Members of the ligand family are straightforward to prepare in one step from 6-hydroxypicolinic acid and the corresponding anilines.

A systematic study of the cross-coupling capability of 4-and 5-substituted 2-phenylthiazoles under Stille conditions is presented. Two cross-coupling options were investigated: 1) combination of thiazolylstannanes with various aryl(hetaryl) halides and, 2) reaction of halothiazoles with PhSn(Bu) 3 as coupling partner. The results obtained from the cross-coupling reactions on the 4- and 5-positions of the thiazole system were compared regarding the influence of the position of the halide (Br, I) and the Bu 3Sn group on both coupling partners. A broad selection of aromatic and heteroaromatic halides was coupled in order to establish a general reactivity platform for this heterocyclic system. Georg Thieme Verlag Stuttgart.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.141305-40-0, Name is 4-Bromo-2-phenylthiazole, molecular formula is C9H6BrNS. In a Article，once mentioned of 141305-40-0, Recommanded Product: 4-Bromo-2-phenylthiazole

Substantial research interests have been focused on cyclic pi-conjugated molecules owing to their unique chemical and physical properties. By constructing hybrid aromatic arrays within these cyclic systems, new series of composite macrocycles would be provided. Our group has been studying the construction of such hybrids by adopting the palladiumcatalyzed direct coupling of heteroaromatics. We herein report the synthesis and characterization of thiophene-thiazole composite macrocycles. X-ray diffraction analyses revealed that some of these coupling products exhibit characteristic helical assemblies in the solid state. Additionally, we synthesized a heteroarene-fused cyclooctatetraene composed of four different heteroaryl fragments.

The arylation of thiazoles in 4- and 5-position was investigated in detail. Suzuki-Miyaura and Stille cross-coupling reactions were tested using thiazoles either as halide or organometal species. The obtained results were critically compared to develop helpful guidelines for selection of the cross-coupling methodology with the best potential for good and reliable results for a given synthetic problem without the need for tedious optimization of reaction parameters.

The synthesis of the title compounds (1) was achieved in two steps starting from readily available 2,4-dibromothiazole (2). In a regioselective Pd(O)-catalyzed cross-coupling step, compound 2 was converted into a variety of 2-substituted 4-bromothiazoles 3 (10 examples, 65-85% yield). Alkyl and aryl zinc halides were employed as nucleophiles to introduce an alkyl or aryl substituent. The Sonogashira protocol was followed to achieve an alkynyl-debromination. Bromo-lithium exchange at carbon atom C-4 and subsequent transmetalation to zinc or tin converted the 4-bromothiazoles 3 into carbon nucleophiles which underwent a second regioselective cross-coupling with another equivalent of 2,4-dibromothiazole (2). The Negishi cross-coupling gave high yields of the 2?-alkyl-4-bromo-2,4?-bithiazoles 1a-g (88-97%). The synthesis of the 2?-phenyl- and 2?-alkynyl-4-bromo-2,4?-bithiazoles 1h-j required a Stille cross-coupling that did not proceed as smoothly as the Negishi cross-coupling (58-62% yield). The title compounds which were accessible in total yields of 38-82% are versatile building blocks for the synthesis of 2,4?-bithiazoles.

2,4-Disubstituted thiazoles by regioselective cross-coupling or bromine-magnesium exchange reactions of 2,4-dibromothiazole

Cross-coupling reactions occur on 2,4-dibromothiazole preferentially at the more electron-deficient 2-position. This fact can be favorably used to prepare 2-substituted 4-bromothiazoles, which serve as precursors for 2,4-disubstituted thiazoles. Protocols for regioselective Negishi and Stille cross-coupling reactions are provided. Alternatively, the title compound can be metalated in 2-position by a halogen-metal exchange reaction. As a supplement to the well-established bromine-lithium exchange, the regioselective bromine-magnesium exchange reaction is presented.

A systematic study of Suzuki-Miyaura cross-coupling reactions on thiazoleboronic esters in the 4- and 5-position

A systematic study of the Suzuki-Miyaura cross-coupling reaction of thiazoleboronic esters under microwave conditions is presented. Boronic acid esters were prepared in the 4- and 5-position of the thiazole ring and subsequently cross-coupled with a number of different (hetero)aryl halides. Yields of the coupling process depended on the reactivity of the boronic acid at the particular position in the thiazole system, as hydrolysis and subsequent deboronation was found to be a major side reaction.
