FIRST PREPARATION OF ALLYL VANADIUM REAGENTS IN A MIXED SOLVENT OF THF AND HMPA (HMPA EQUALS HEXAMETHYLPHOSPHORIC TRIAMIDE) AND THEIR APPLICATION TO ALLYLATION OF CARBONYL COMPOUNDS

摘要

Allylation of carbonyl compounds with allyl bromide mediated by a vanadium(II) complex in a mixed solvent of THF and HMPA (HMPA = hexamethylphosphoric triamide) has been accomplished. Coordination of HMPA to a vanadium metal is essential for the stabilization of the allyl vanadium species. Copyright (C) 1996 Elsevier Science Ltd [References: 13]
