Abstract: Insertion or coordination copolymerization of ethylene with di-substituted olefins is challenging and the choice of di-substituted mono-functional olefin versus di-substituted di-functional olefin (DDO) appears to be decisive. Here we show that DDO-inserted species are amenable… read more here.

DOI: 10.1021/acscatal.8b04707
Abstract: A possible involvement of radicals in catalytic insertion chain growth remains elusive, albeit it could account for thus far inconclusive experimental observations and enable yet unachieved synthetic reaction schemes. This work shows that radicals present,… read more here.

DOI: 10.1126/science.abi4407
Abstract: Polyethylene production through catalytic ethylene polymerization is one of the most common processes in the chemical industry. The popular Cossee-Arlman mechanism hypothesizes that the ethylene be directly inserted into the metal–carbon bond during chain growth,… read more here.
