| Abstract: | Summary Monocarbonyls of manganese(I) with two chelating diphosphinestrans-[Mn(CO)(diphos)2(L)]A, [diphos = 1,2-bis(diphenylphosphino)ethane, dppe, or bis(diphenylphosphino)methane, dppm; L=nitriles, NCR (NCMe, NCEt, NCPh, or NCCH2Ph), dinitriles, NCGCN (NCCH2CN, NCCH2CH2CN, oro-(NC)2C6H4), isonitriles, CNR, (CNPh, or CNBut); A = C1O4– or PF6–],trans-[(Mn(CO)(dppm)2)2( -NCCH2CH2CN)](ClO4)2 and the monocarbonyl with one diphosphine,mer-[Mn(CO)(dppe)(CNBut)3]ClO4, have been prepared fromtrans-[Mn(CO)(diphos)2Br].In this paper we have adopted the convention that gives positive shift to signals at higher frequency of ext. H3PO4. |
