Abstract
Ketones undergo soft enolate formation and acylation on treatment with MgBr2ˇOEt2, i-Pr2NEt, and various acylating agents to give 1,3-diketones. A particularly simple and efficient acylation with N-acylbenzotriazoles and O-Pfp esters can be conducted in untreated, reagent-grade CH2Cl2 open to the air.
