Webor much stronger basicity than LDA and LHMDS. Contrary to organic strong bases, weak secondary and primary amines can be successfully employed for the a-func-tionalization of non-activated ketones in which the key inter-mediate is not an enolate but an enamine. Stork was a pioneer in this eld of enamine chemistry where an equimolar amount Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH3)3Si]2NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.
