DOI: 10.1021/acs.accounts.1c00368
Abstract: ConspectusTitanium is an attractive metal for catalytic reaction development: it is earth-abundant, inexpensive, and generally nontoxic. However-like most early transition metals-catalytic redox reactions with Ti are difficult because of the stability of the high-valent TiIV… read more here.

DOI: 10.1021/acs.organomet.8b00097
Abstract: The extreme π-loading of a (CCC-NHC) pincer Ta(V) bis(imido) complex was previously reported. This complex catalyzes the cyclization of α,ω-aminoalkenes (2,2-diphenylpent-4-en-1-amine) to produce three different products in varying proportions: cyclic imine from oxidative amination (OA),… read more here.
