Abstract
Reaction of [Ru(CO)2(PPh3)3] with [Cd(CF3)2(MeOCH2CH2OMe)] produces the zerovalent CF2-complex, [Ru(CF2)(CO)2(PPh3)2]; X-ray crystal structure determination reveals very distorted trigonal bipyramidal geometry and an RuC distance of 1.83(1)Å, and reaction indicate that when compared with an RuII CF2-complex, the CF2-ligand in the zerovalent compound has greatly reduced reactivity towards nucleophiles and in fact reacts with the electrophiles HCL and Ag+ giving [Ru(CF2H)Cl(CO)2(PPh3)2] and [[graphic omitted]{H2O})(CO)2(PPh3)2]+, respectively.Keywords
