Minimalist N-heterocycliccarbeneboranes 1,3-dimethylimidazol-2-ylideneborane and 2,4-dimethyl-1,2,4-triazol-3-ylideneborane are readily available and have low molecular weights. They exhibit superior performance to first-generation NHC−boranes, providing improved yields in reductions of xanthates and related functional groups.

Synthesis was performed of (3S)-3-methyldecen-1-ol and (4S)-4-methylundecen-1-ol, chiral alcohols with a methyl-branched carbon skeleton. The possibility of their application in asymmetric syntheses of insect pheromones was demonstrated.
