ChemInform Abstract: Transition-Meta1-Substituted Acylphosphanes and Phosphaalkenes.
Abstract
Reaction of the title compound (I) with acyl chlorides (II) leads to the phosphaalkenyl complex (IIIa), to (IIIb) and the diacylphosphido complex (IVb), or only to the diacylphosphido derivative (IVc) depending on ′the acyl substituent R. The monoacylphosphido Complexes (V) are generated by reaction of (I) with the acyl chlorides (II) in the presence of ethanol.
ChemInform Abstract
Reaction of the title compound (I) with acyl chlorides (II) leads to the phosphaalkenyl complex (IIIa), to (IIIb) and the diacylphosphido complex (IVb), or only to the diacylphosphido derivative (IVc) depending on ′the acyl substituent R. The monoacylphosphido Complexes (V) are generated by reaction of (I) with the acyl chlorides (II) in the presence of ethanol. Their lithiation by LiMe and subsequent acylation or silylation convert (V) into the diacylphosphido complex (IVa) or into the phosphaalkenyl Complexes (IIIa)-(IIIc), respectively.
