The other half of the Michaelis–Arbuzov reaction: A new synthetic route to tertiary phosphorus–carbon bond formation
摘要:
A first-row transition metal assisted modification of the Michaelis-Arbuzov rearrangement has been discovered that allows the reaction to take place under ambient conditions using a mild phosphine nucleophile. This reaction has been used as a novel synthetic strategy for the assembly of P-C bonds in typically difficult to construct 3-methylpyridyl substituted phosphine and phosphonium ligands. Metal complexes of these ligands were characterized crystallographically. One of the products also contains the previously unknown pyridyl FeCl3- species. (c) 2006 Elsevier B.V. All rights reserved.
