A NOVEL INTRAMOLECULAR INSERTION OF A METAL ACYL GROUP INTO AN ORGANIC KETONE

[[abstract]]Synthesis of metal-butyrolactones via insertion of a metal acyl bond into an organic ketone is demonstrated, and the crystal structure of one example is reported; labelling experiments exclude the possibility that this insertion is initiated by intramolecular attack of the enol on the acyl group.[[fileno]]2010327010052[[department]]化學
