The reaction of (Me3Si)2CHPCl2 or (Me3Si)3CPCl2 with (2,4,6-t-Bu3-C6H2)PH2 in the presence of DBU (1,5-diazabicycloundec-5-ene) affords the unsymmetrical diphosphene, (Me3Si)2CHP=P(2,4,6-t-Bu3-C6H2).
STRUCTURAL ISOMERIZATION OF P-(p'-TRIMETHYLSILYLPHOSPHINO)-METHYLENEPHOSPHINE TO DIPHOSPHENE: A NEW APPROACH TO THE SYNTHESIS OF UNSYMMETRICAL DIPHOSPHENES

The reaction of Pchloro-bis(trimethylsilyl)methylenephosphine 1 with LiP(SiMe3)But, LiP(SiMe3)Ar and LiN(SiMe3)Ar (Ar = 2,4,6-But3C6H2) have been investigated.Depending upon the steric bulk of the phosphorus substituent in starting silylphosphine, the product was either P-(P'-trimethylsilylphosphino)methylenephosphine 3 or the structurally rearranged diphosphene 4.The latter conversion constitues the first example of P-phosphinomethylenephosphine->diphosphene isomerization.The product of the reaction of 1 with LiN(SiMe3)Ar exists in the from P-amino-methylenephosphine 6.
