Diazobutanol complexes of molybdenum and tungsten from the reaction of bis[1,2-bis(diphenylphosphino)ethane]bis(dinitrogen)molybdenum or -tungsten with tetrahydrofuran in the presence of alkyl bromides

Abstract

Complexes of the type [M(N₂)₂(dppe)₂][M = Mo or W; dppe = 1,2-bis(diphenylphosphino)ethane] react with tetrahydrofuran in the presence of alkyl bromides to form [MBr(NN–[graphic omitted]H₂)(dppe)₂] which are converted by H⁺ into [MBr(N–NCHCH₂CH₂CH₂OH)(dppe)₂]⁺. The mechanism of this reaction is discussed.
