Application In Synthesis of 2,6-Dimethyl-3,5-heptanedione. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 2,6-Dimethyl-3,5-heptanedione, is researched, Molecular C9H16O2, CAS is 18362-64-6, about Silica sulfuric acid mediated acylation of amines with 1,3-diketones via C-C bond cleavage under solvent-free conditions. Author is Guo, Ruiqiang; Zhu, Chuanlei; Sheng, Zhe; Li, Yanzhe; Yin, Wei; Chu, Changhu.
An inexpensive silica sulfuric acid (SSA) mediated acylation of amines with 1,3-diketones via C-C bond cleavage was realized under solvent and transient metal free conditions. In this chem., both catalytic aerobic oxidative and hydrolyzed C-C bond cleavage were coexisted. Furthermore, the activation of mol. oxygen by non-transient metal catalyst (SSA) was disclosed.
