The reaction of Cp1(CO)2MP:PR [I; M = Fe, Ru; R = 2,4,6-(Me3C)3C6H2; Cp1 = h5-pentamethylcyclopentadienyl] with Me2S(O):CH2 in THF at 20 Deg afforded the transition-metal-functionalized diphosphiranes II. Similarly the 1st 1,2-diphosphaspiro[2.2]pentanes III (same M, R) were synthesized from I and diphenylsulfonium cyclopropanide. The crystal and mol. structure of III (M = Fe) was detd.
