A series of racemic or stereochemically labile chiral borate anions based on the 2,20-biphenol motif was investigated. All borates were homochiral in the solid state, although in some cases the heterochiral diastereomers were computed to be thermodynamically preferred (DFT). The crystallographic preference for the homochiral diastereomer was attributed to its lower bulk, higher molecular symmet...

In the first part of this review, secondary carbon-carbon bond formation by using allylic coupling reactions with aryl and alkenyl borates is presented. Early investigations have revealed suitability a nickel catalyst [RTB(OMe)3]Li (RT: transferable group). Due to their low reactivity, were converted more reactive congeners possessing an alkanediol ligand, such as 2,3-butanediol 2,2-dimethyl-1,...
