| Research Abstract |
Deuteride reduction reactions of carbonyl compounds were developed by using the umpolung of heavy water under mild conditions without the presence of a transition metal. Ate-type hexacoordinated phosphorus compounds bearing two P-H bonds were synthesized as stable compounds. Two isomers around the phosphorus atom were isolated. Both isomers showed H-D exchange reactivity toward heavy water and hydride reduction reactivity toward carbonyl compounds. The reactivities of one isomer differ from those of the other isomer. Reaction conditions for the one-pot reaction of these two reactions were found, and the carbonyl compounds were formally reduced with heavy water. Therefore, a nucleophilic reductive deuteration method by using heavy water were successfully developed.
