These unique characteristics of K (1PBH) stimulated us to investigate other members of the potassium trialkoxyborohydride family. Accordingly, we undertook a study to develop a general procedure for the synthesis of potassium trialkoxyborohydrides in tetrahydrofuran (THF) with representative trialkoxyboranes of different steric requirements and to examine their stereoselectivities in the reduction of cyclic ketones.
