Outline of Final Research Achievements

In this study, we investigated the synthesis, characterization, and reactivity of stimuli-responsive low-coordinate compounds of main group elements by taking advantage of the steric effects of the fused-ring bulky Rind groups (Rind = 1,1,3,3,5,5,7,7-octa-R-substituted s-hydridacen-4-yl). A complete series of diaryltetrylenes, (Eind)2E: (E = Si, Ge, Sn, and Pb), were synthesized, and their molecular structures were confirmed by X-ray crystallography. The first diarylstannanone, (MPind)2Sn=O, was obtained by the reaction of (MPind)2Sn: with N2O gas, whose X-ray structure exhibits a planar tricoordinate tin center with a very short Sn-O bond. We also examined the oxygen atom transfer (OAT) reaction of germanone, (Eind)2Ge=O, with isocyanide involving the cleavage of Ge-O bond and their application to the novel germanium catalytic system. We performed many joint researches of stimuli-responsive low-coordinate compounds and their application to the ligands for transition metal complexes.
