Charged! Combining MeBABAR‐Phos and methyl triflate affords an amino‐stabilized phosphiranylium ion (see picture; C gray, N blue, P orange), which undergoes various nucleophilic addition reactions to give P‐substituted phosphiranes and an N‐heterocycliccarbenestabilized phosphiranylium cation.

The heterogeneousdechlorination of alkyldichlorophosphanes by Mgmetal at 600 K yields chemidesorbed products which include penta-alkylcyclopentaphosphanes (RP)5, in addition to Rn PH3–n,R2P–PR2,P4,RH, and R–R, and thus provides evidence for surfacephosphinideneintermediates [RP → Mg].
镁金属在600 K下对烷基二氯膦进行多相脱氯,除R n PH 3– n,R 2 P–PR 2,P 4,RH和R–R外,还产生了化学吸附产物,其中包括五烷基环五膦(RP)5,因此为表面次亚膦酸酯中间体[RP→Mg]提供了证据。
Chlorophosphanyl and dichlorophosphanyl alkylidene- and benzylidenephosphoranes 6 and 8 are converted by reaction with LiAlH4 to the respective phosphanes 7 and 9. The former can be isolated, but decompose on heating or on protonation to give the ylidyl diphosphane 11 and the phosphonium ylide or phosphonium salt, respectively. The final products are the cyclooligophosphanes 15−17. Only the C-tert-butyl

synthesized from the reaction of bis(1,5-cyclooctadiene)nickel(0) ([Ni(cod)2 ]) with organocyclophosphine and trialkylphosphine. We found that [Ni(cod)2 ] cleaves the organocyclophosphine P-P bonds to generate phosphinidene groups, establishing the cyclic molecules as valuable precursors for making charge-neutral molecular clusters passivated by two-electron donor capping ligands. The formation of the cluster
