A highly diastereoselective carbon-carbon bond-forming reaction involving the tandem coupling of benzyltriboronates, enoates, and alkyl halides is described. This method was enabled by the discovery of α-diimine nickel catalysts that promote the chemoselective triborylation of benzylic C(sp3)-H bonds using B2Pin2 (Pin = pinacolate). The C-H functionalization method is effective with methylarenes and

Synthetic approaches are discussed to a preparation of binuclear trimethylacetatozinc complexes containing an M-2(mu-OOCR)(2)L-4 binuclear fragment, which is found in the active site of native metalloenzymes.
