The acyclic dialkylstannylene (Me(3)Si){Me(2)P(BH(3))}CHSn (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))}CHSn(Me)(I) (8), (Me(3)Si){Me(2)P(BH(3))}CHSn(CH(2)CMe(3))(I) (9), and (Me(3)Si){Me(2)P(BH(3))}CHSn(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)CHSn(OCPh=CPhO) (11) and {Me(2)P(BH(3))}(Me(3)Si)CHSn(S) (12), respectively, as confirmed by multinuclear NMR spectroscopy and elemental analysis.
无环二烷基锡 (Me(3)Si){Me(2)P(BH(3))}CHSn(7)与碘化甲基、新戊基碘或溴化苄反应,分别生成相应的氧化加成产物 (Me(3)Si){Me(2)P(BH(3))}CHSn(Me)(I)(8)、(Me(3)Si){Me(2)P(BH(3))}CHSn(CH(2)CMe(3))(I)(9)和 (Me(3)Si){Me(2)P(BH(3))}CHSn(CH(2)Ph)(Br)(10)。8、9 和 10 的晶体结构表明不存在紧密的 B-H…Sn 接触。此外,7 与二苯甲酮或硫反应,分别生成 {Me(2)P(BH(3))}(Me(3)Si)CHSn(OCPh=CPhO)(11)和 {Me(2)P(BH(3))}(Me(3)Si)CHSn(S)(12),这一点通过多核 NMR 光谱和元素分析得到了证实。
