Herein, the synthesis and characterization of bicyclic (alkyl)(amino)carbene (BICAAC)-stabilized phosphinidenes (1-4) are reported. Compounds 1-3 were obtained by reacting trihalophosphine [PX, X = Cl (1), Br (2), I (3)] with BICAAC in THF. A BICAAC-stabilized bis-phosphinidene (4) was obtained from the reduction of compound 2. All four compounds were characterized by X-ray crystallography and heteronuclear NMR spectroscopy. Theoretical calculations indicated the predominant C(carbene)P double bond characteristic in compounds 1-4.
本文报道了双环（烷基）（氨基）卡宾（BICAAC）稳定的磷烯（1-4）的合成与表征。化合物1-3是通过三卤化膦[PX，X = Cl（1），Br（2），I（3）]与BICAAC在四氢呋喃中反应得到的。化合物2经还原得到BICAAC稳定的双磷烯（4）。所有四种化合物均通过X射线晶体学和异核核磁共振光谱进行了表征。理论计算表明化合物1-4中主要存在C（卡宾）-P双键特征。
