title: Oxidation reactions of a phosphine-borane-stabilised dialkylstannylene.
abstract: The acyclic dialkylstannylene [(Me(3)Si){Me(2)P(BH(3))}CH](2)Sn (7) reacts with any of methyl iodide, neopentyl iodide or benzyl bromide to yield the corresponding oxidative addition products [(Me(3)Si){Me(2)P(BH(3))}CH](2)Sn(Me)(I) (8), [(Me(3)Si){Me(2)P(BH(3))}CH](2)Sn(CH(2)CMe(3))(I) (9), and [(Me(3)Si){Me(2)P(BH(3))}CH](2)Sn(CH(2)Ph)(Br) (10), respectively. The crystal structures of 8, 9, and 10 reveal that there are no close B-H...Sn contacts. In addition, 7 reacts with benzil or elemental sulfur to yield [{Me(2)P(BH(3))}(Me(3)Si)CH](2)Sn(OCPh=CPhO) (11) and [{Me(2)P(BH(3))}(Me(3)Si)CH](2)Sn(S) (12), respectively, as confirmed by multinuclear NMR spectroscopy and elemental analysis.
