Page column 14-15, (2010/02/05)
The present invention relates to compounds in which a transition metal is complexed with two ligand systems and the two systems are reversibly bonded together by at least one bridge consisting of a donor and an acceptor, at least one substituent on the acceptor group being a fluorinated aryl radical, to the use of these compounds as catalysts and to a process for the polymerization of olefins.

Compounds of the series (C6H5)n(C6F5) 3-nSnMn(CO)5 (n = 0, 1, 2) have been prepared by reactions of C6F5Li or C6F5MgBr with (C6H5)nCl3-nSnMn(CO)5. Carbonyl stretching frequencies are assigned and approximate force constants given. A linear relation between carbonyl stretching frequency and electronegativity of substituents on tin suggests a Pauling electronegativity of about 2.4 for the C6F5 group. The compounds (C6F5)2Sn [Mn(CO)5]2 and (OC)5Mn(C6H5)2Sn-Sn(C 6H5)2Mn(CO)5 have also been prepared, the latter containing a four-metal chain. In both of the bis-pentacarbonylmanganese compounds, the number of strong carbonyl bands is greater than five, suggesting that a substantial coupling of Mn(CO)5 groups takes place across the intervening tin atoms.
