Reaction of 1-{(pentamethylcyclopentadienyl)(dicarbonyl)ferrio}-2-(2,4,6-tri-tert-butylphenyl)diphosphene with 1,2,4-triazoline-3,5-diones: formations and structures of the first 1,2-diaza-3,4-diphosphetidines and E,E-1,7-dioxa-4,5,10,11-tetraaza-3,4,8,9-tetraphosphacyclododeca-5,11-diene
Reaction of [(η5-C5Me5)(CO)2Fe–PP–MeS*]1(Mes*= 2,4,6-But3C6H2) with 1,2,4-triazoline-3,5-diones [[graphic omitted](O)]2(a: R = Ph; b: R = 4-EtOC6H4) in benzene at ambient temperature affords the first 1,2-diaza-3,4-diphosphetidines as part of the bicyclic compounds 4, whereas in diethyl ether solution the twelve-membered macrocycle 5 is obtained.

In the reaction with nucleophiles of the type M′[M(CO)2C5R5] (M′ Na, K; M Fe, Ru; R H, CH3), the pentamethylcyclopentadienyl (Cp★) ligand in the known diphosphenes Cp★PPMes★ and Cp★PPCp★, and in the arsaphosphene Cp★AsPMes★ acts as a nucleofugal leaving group. This behaviour opens an alternative synthetic route to transition-metal substituted diphosphenes, arsaphosphenes, and tetraphospha-bicyclobutanes
在与M'[M(CO)2 C 5 R 5 ](M'Na,K;MFe,Ru;RH,CH 3)类型的亲核试剂反应中,五甲基环戊二烯基(Cp★)配体在已知的二膦Cp★PPMes★和Cp★PPCp★中,以及在亚磷phosphCp★AsPMes★中充当核真菌离去基团。此行为为过渡金属取代的二膦,亚砷膦和四磷-双环丁烷开辟了另一条合成途径。
