DIORGANOPHOSPHINOALKYL-DIMETHYLZINNCHLORIDE: SYNTHESE, STRUCTUR UND REAKTIONSVERHALTEN

Phosphinoalkylchlorostannanes of the type Me2Sn(Cl)(CH2)nPR1R2 (n=2,3) (I-VIII) are synthesized by a redistribution reaction of the tetraorganostannanes Me3Sn(CH2)nPR1R2 (n=2,3) with trimethyltin chloride.In non-coordinating solvents the tin atom in I-IV is tetracoordinated, whereas NMR data indicate an intramolecular Sn-P interaction for V-VIII.In the solid state compound III exists as an 1:1 adduct with trimethyltin chloride.With methyl iodide compounds I-VIII form the phosphonium stannates Me2Sn-(Cl) (I) (CH2)nP+R1R2Me (XI-XIII).Compounds I-VIII are suitable starting materials for the synthesis of the tin hydrides Me2Sn(H)(CH2)nPR1R2 (XIV-XVI) and the distannanes 1R2>2 (XVII-XIX).The reaction of I-VIII with sodium in liquid ammonia or with lithium in THF, respectively, yields solutions of the corresponding alkali stannides Me2Sn(M)(CH2)nPR1R2 (M=Li, Na).
