Web2‐Dicyclohexyl‐ and 2‐diphenylphosphinophenol, CCHH and PPHH, react with Ni(1,5‐COD) 2 to form catalysts for polymerization of ethylene in or copolymerization with α‐olefins. The more P‐basic CCHH/Ni catalyst allows concentration‐dependent incorporation of olefins to give copolymers with isolated side groups and higher molecular weights, whereas the … WebJul 21, 2015 · The P,O-type phosphinophenol proligands (1·H, 2-PPh2-4-Me-6-Me-C6H2OH; 2·H, 2-PPh2-4-Me-6- (t)Bu-C6H2OH) readily react with one equiv. of ZnEt2 to afford in high yields the corresponding Zn (II)-ethyl dimers of the type [ (κ (2)-P,O)Zn-Et]2 (3 and 4) with two μ-OPh bridging oxygens connecting the two Zn (II) centers, as determined by X-ray …
