Although, π-Loading is concept that has been explored since the early nineties, it has seen a resurgence of late. We have recently reported the first example of a CCC-NHC pincer Ta complex. A bis(imido) derivative was prepared to test the extreme-π loading hypothesis, in which the orbital interactions are maximized. The hypothesis will be presented and discussed. The original complex was reported to be active for the catalytic oxidative amination of alkenes with concommitant transfer hydrogenation. Further studies relating to C-H bond activation will be reported.
