Carbonyllithium chemistry. Intramolecular conversion of an acyllithium via the utilization of an anionic 1,2-stannyl rearrangement
摘要:
The reaction of alpha-stannylmethyllithium with CO (1 atm) generates the acyllithium that smoothly undergoes anionic 1,2-stannyl rearrangement at -78 degrees C to give the enolate derivative of acyltin. The rearrangement of the stannyl group is much faster than that of the silyl group. (C) 1999 Elsevier Science S.A. All rights reserved.
