The reactions of a phosphavinyl Grignardreagent, [CyPC(But)MgCl(OEt2)] Cy=cyclohexyl, with a variety of main group 13, 14 and 16 mono-halide compounds have been investigated. When the Grignardreagent is reacted with bromocatecholborane the terminal phosphavinyl complex, [(C6H4O2)BC(But)PCy}], is formed. Related terminal phosphavinyl tin and gallium complexes, [R3SnC(But)PCy}], R=Me or Bun and
已研究了磷乙烯基格氏试剂[CyPC(Bu t)MgCl(OEt 2)] Cy =环己基与各种主族13、14和16单卤化物的反应。当格氏试剂与溴邻苯二甲硼烷反应时,形成末端磷乙烯基复合物[(C 6 H 4 O 2)B C(Bu t)PCy}]。相关的末端磷酰基乙烯基锡和镓络合物,[R 3 Sn C(Bu t)PCy}],R = Me或Bu n和[IGa C(Bu t)PCy} 2 ],已经通过类似的方法制备。 。格氏试剂与PhSeCl的反应已经得到了新的λ 5,λ5-二磷酸,[(Bu t)CP(Cy)(SePh)} 2 ],讨论了其形成机理。还描述了磷乙烯基硒化合物[[C 8 H 4 O 2 N]PC(Bu t)(SePh)]的制备。所有化合物均已进行了光谱表征,并已通过晶体学鉴定。
