摘要: Abstract The phosphidomanganates Li 2 [(OC) 4 MnPR 1 ] ( 3a–c ) (R = Ph a ), Cy b i-Pr c )) are obtained by double deprotonation of HMn(CO) PR H 2a–c with n-BuLi. Replacement CO in 5 the phosphanes HPR affords . phosphamanganacyclopropanes (OC) M nPR C HR 4a,b, 5a,b Me and diphosphamanganacyclopropanes R 3 , 6a, 7c, 8a,b 9a–c 2,4,6-(t-Bu) 6 7 Cy( 8 t-Bu 9 accessible action geminal dihalides CHCl dichloroorganylphosphanes PCl respectively, on kinetic stability 6–9 depends size substituents position ν(PP) IR spectra J (PP) coupling constants 31 P“ H”-NMR indicate significant P P-π bonding character.
