DOI: 10.1021/acs.organomet.8b00755

Abstract: Resting/dormant benzyl- and allyl-type Ti(IV) complexes formed under α-olefin polymerization conditions have been detected and characterized by NMR. Experimental and computational evidence supports a formation mechanism via reversible Ti–C bond homolysis rather than “classical” σ-bond… read more here.

recommendations! Published in 2019 at "Organometallics"

DOI: 10.1021/acs.organomet.9b00197

Abstract: Highly enantioselective Hiyama cross-coupling reactions have been achieved through rhodium(I)-catalyzed dynamic kinetic asymmetric transformations between aryl siloxanes and cyclic racemic allyl halides. This process affords valuable enantiomerically enriched aryl-substituted cyclic allyl products and is compatible… read more here.
