Abstract: | Complexes Cr(CO)2L(C6Me6-nHn), n = 0-3, L = CO and PPh3, react with NOPF6 in methanol/toluene to give Cr(CO)L(NO)(C6Me6-nHn)] PF6, n = 0-3, L = CO; n = 0, L = PPh3, and these react with nucleophiles (X-) to give cyclohexadienyl derivatives Cr(CO)2(NO)(C6Me6-nHnX); the compounds Cr(CO)2(PhCCPh)(C6Me6-nHn) react with NOPF6 to yield Cr(H)(CO)2(PhCCPh)(C6Me6-nHn)] PF6, n = 0 and 1. |
