The synthesis and characterization of an (arsino)phosphaketene, As(PCO){[N(Dipp)](CH2)}2 (Dipp=2,6‐diisopropylphenyl) is reported along with its subsequent reactivity with B(C6F5)3. When reacted in a stoichiometric ratio, B(C6F5)3 drove the insertion of the P=C bond of the phosphaketene into one of the As−N bonds of the arsino functionality, affording an acid‐stabilized, seven‐membered, cyclic arsaphosphene. In contrast, when catalytic amounts of B(C6F5)3 were employed, dimeric species, which formed through a formal [2+2] cycloaddition of the cyclic arsaphosphene, were generated. The cyclic arsaphosphene product represents the first example of such a compound in which the two substituents are arranged in a cis‐configuration.

B（C6F5）3使能的环状顺式Arsaphosphene的合成
报告了（arsino）磷烯（As（PCO）{[N（Dipp）]（CH 2）} 2（Dipp = 2,6-二异丙基苯基）的合成和表征，以及其随后与B（C 6 F 5）3。当以化学计量比进行反应时，B（C 6 F 5）3驱使磷烯酮的P = C键插入到Arsino官能团的As-N键之一中，从而提供了酸稳定的七元原子，环状亚磷phosph。相反，当催化量的B（C 6 F 5）3当使用二聚体时，生成了二聚体，该二聚体是通过环状砷化膦的正式[2 + 2]环加成反应而形成的。环状a磷鎓产物代表了这样一个化合物的第一个例子，其中两个取代基排列成顺式构型。
