Molecular Structures of the Phospha-Wittig Reaction Intermediate: Initial Step in the Synthesis of Compounds with a C═P–P Bond as Products in the Phospha-Wittig Reaction

Abstrakt

The phospha-Wittig reactivity ofβ-diketiminate titanium(III) complexes with phosphanylphosphido ligands was investigated. The reactions of [MeNacNacTi(Cl){η2-P(SiMe3)-PtBu2}] and [MeNacNacTi(Cl){η2-P(SiMe3)-P(Ph)tBu}] with acetone conducted in toluene solution under mild conditions led to the phospha-Wittig intermediates [{(ArN=C(Me)CHC(Me)=NAr)(C(Me)2O}Ti(Cl){PtBu2-P(SiMe3)C(Me)2O}] (1) and [{(ArN=C(Me)CHC(Me)=NAr) (C-(Me)2O}Ti(Cl){P(Ph)tBu-P(SiMe3)C(Me)2O}] (2). Complexes 1 and 2 were isolated in the crystalline form and characterized for thefirst time. Furthermore, the isolated complexes1and2dissolved in THF solution led to the phospha-Wittig reaction products - phosphanylphosphaalkenes tBu2P−P=C(Me)2(1a) and (Ph)tBuP−P=C(Me)2(2a)
