Stereochemistry of the carbonylation, carbethoxymethylation, and .gamma.-propanalation reactions of organoboranes. Substitution reactions at carbon that proceed with retention of configuration
It has been demonstrated by means of spectroscopic studies involving cyclizable alkyl halides that lithium dimethylcuprate can react with organichalides by a single electron transfer pathway.

biomass-derived carbonyl compounds is an alternative to condensation chemistry for supplying products with chain length >C6 for biofuels and renewable materials production. Kolbe coupling of biomass-derived levulinicacid is used to obtain 2,7-octanedione, a new platform molecule only two low process-intensity steps removed from raw biomass. Hydrogenation to 2,7-octanediol provides a chiral secondary diol
