Outline of Final Research Achievements

Throughout this research, we obtained the following research results. (1) an ate complex of Li having two boryl anions can deprotonate H2 and benzene, boryl substituted alcohols induce Brook-type rearrangement under basic conditions, nBuLi adducts, radical anion, and dianion derived from a boryl-substituted diphosphene can be stabilized by the substituent effect of boryl groups, (2) an unsymmetrical diborane(4) cleaves the triple bond of CO and isocyanide, the unsymmetrical diborane(4) reacts with alkynes to give the corresponding diborylalkenes, unsymmetrical diborane(4) reacts with isocyanide to induce a ring contraction of Bpin, symmetrical diborane(4) directly reacts with H2.
