Cobalt dialkyl and bis(carboxylate) complexes bearing α-diimine ligands have been synthesized and demonstrated as active for the C(sp3)-H borylation of a range of substituted alkyl arenes using B2Pin2 (Pin = pinacolate) as the boron source. At longer reaction times, rare examples of polyborylation were observed, and in the case of toluene, all three benzylic C-H positions were functionalized. Coupling benzylic C-H activation with alkyl isomerization enabled a base-metal-catalyzed method for the borylation of remote, unactivated C(sp3)-H bonds.

(graph presented) A simple, asymmetric synthesis of tetramic acid derivatives is described in this paper. The key step is a carbonyl transfer from carbonyldiimidazole (CDI) to α-diimines (I) to form N-alkyl-4-alkylamino-5-methylenepyrrol-2-ones (II). In t

Diazadienes (DAD) (with R1, R2 = H, CH3 and R3, R4 = alkyl) form nickel complexes 1-14 with composition (DAD)2Ni.They can be prepared by ligand substitution from other Ni(0) compounds or, preferably, b
