CATALYSTS WITH A DONOR-ACCEPTOR INTERACTION

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.

Method for purifying fluoroaryl metal compound

In a method for purifying a fluoroaryl metal compound of the present invention, magnesium halide is precipitated and removed from a solution containing the fluoroaryl metal compound, the magnesium halide, and an ether solvent. Or, the magnesium halide is removed by treating the solution with an acid. Examples of the method include: a method in which a solvent which has a boiling point higher than that of the ether solvent contained in the solution and which does not dissolve the magnesium halide is heated to a temperature higher than the boiling point of the ether solvent, then the ether solvent is distilled out with the solution being added to the solvent; and a method in which the solution and an aqueous solution containing an acid are mixed and stirred, then allowed to stand so as to be separated into an organic layer containing the fluoroaryl metal compound and an aqueous layer containing the magnesium halide and the acid. In this manner, a highly pure fluoroaryl metal compound having no impurities can be purified easily and inexpensively.

Organometallic compounds with metal-metal bonds. IX. Pentafluorophenyltin derivatives of manganese carbonyl

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.
