While activation of tungsten bis(imido) complexes [WCl2(NAr)2(dme)] with EtAlCl2 affords active, and moderately selective ethylene dimerization catalysts, addition of Et3N or Oct4NCl leads to a doubling in productivity and activity, along with increa

The selective dimerisation of 1-hexene to dodecenes was accomplished using catalysts generated from a tungsten mono- [WCl4(NR)(thf)] or bis- [WCl2(NR)2(dme)] imido complex following activation with EtAlCl2. These catalytic systems achieve 1-hexene di

The ethylene dimerization performance of a range of bis(imido)tungsten pre-catalysts, after activation with aluminum co-catalysts, has been assessed. The best performing system achieved an activity of 409,410 (mol C2H4)(mol W)–1h–1 [79.6 wt% 1-bu

Desilylation of the 2-phosphinophosphinine 2-PPh2-3-Me-6-SiMe3-PC5H2 with HCl gave 2-PPh2-3-Me-PC5H3, demonstrating the late-stage modification of this bidentate heterocyclic ligand. Group 6 metal carbonyl complexes of these ligands showed κ2 bindin

The interaction of triethylaluminum (TEA) with a solution of the paramagnetic Cr(I) bis(phosphine) complex [Cr(CO)41][Al(OC(CF3)3)4] (1 = Ph2PN(iPr)PPh2) has been studied using EPR and DFT. It was found that the TEA is responsible for the complete re

Charm D-meson production in 360 GeV π−p interactions has been studied using the high-resolution hydrogen bubble chamber LEBC and the European Hybrid Spectrometer. The data show evidence for leading quark effects both in the number of D-meson types
