Abstract
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 chemistry, both catalytic aerobic oxidative and hydrolyzed C-C bond cleavage were coexisted. Furthermore, the activation of molecular oxygen by non-transient metal catalyst (SSA) was disclosed.
