Ethylene-tetrafluoroethylene (ETFE) cotelomer iodides and their transformation to surface protection intermediates

A new class of fluorotelomers was synthesized via the cotelomerization of ethylene and tetrafluoroethylene (TFE) with 1H,1H,2H,2H-perfluoroalkyl iodides. The telomerization led to ethylene-tetrafluoroethylene (ETFE) cotelomer iodides with the incorporation of ethylene and TFE in the cotelomer chain in an alternating fashion. By controlling the reaction parameters such as total pressure, temperature, feed ratio of the monomers, initiator feed, and conversion rate, eight-carbon cotelomer iodide or higher cotelomers could be produced preferably. The ETFE cotelomer iodides were transformed to a variety of intermediates such as alcohols, azides, amines and thiols, precursors useful to make surface modification agents.

Copper salt-catalysed reaction of perfluoroalkyl halides with olefins

Perfluoroalkyl halides react with olefins in the presence of copper acetate and hydrazine to give 1,2-addition products.

Process for addition of haloalkanes to alkenes catalyzed by an organophosphite compound

A process for catalytic addition of haloalkanes to alkenes involving the step of reacting the haloalkane with the alkene in the presence of a catalyst. The catalyst is an organophosphite compound represented by the following formula: P(ORa)(ORb)(ORc), where Ra, Rb, and Rcare each an alkyl group or an aralkyl group. The haloalkane is as follows: (i) CR1R2R3R4, wherein (a) each of R1, R2, R3and R4is selected from the group consisting of a chlorine atom, a bromine atom or an iodine atom; or (b) R1is selected from the group consisting of a linear alkyl group; a halo-substituted linear alkyl group; an aralkyl group; an aralkyl group substituted with at least one of a halogen atom on the alkyl portion thereof or a halogen atom, alkyl group, alkoxy group or —CO2R10wherein R10is a C1-C4alkyl group on the aryl portion thereof; an aryl group and an aryl group substituted with at least one of a chlorine atom, a fluorine atom, an alkoxy group or a —CO2R11group, wherein R11is a C1-C4alkyl group; and R2, R3and R4are as follows: R2is an iodine atom and R3and R4are each a halogen atom except R3and R4are not each a bromine atom or R2and R3are each a bromine atom and R4is a halogen atom. The catalyzed addition of the haloalkane to the alkene proceeds without any other components present in an excess amount, by weight, of the combined amount of the haloalkane, alkene and organophosphite catalyst compound.
