Abstract
An inexpensive silica sulfuric acid (SSA) mediated acylation of amines with 1,3-diketones via CC bond cleavage was realized under solvent and transient metal free conditions. In this chemistry, both catalytic aerobic oxidative and hydrolyzed CC bond cleavage were coexisted. Furthermore, the activation of molecular oxygen by non-transient metal catalyst (SSA) was disclosed.
