| Research Abstract |
The present co-operative research has been carried out by the following four groups : (1)molecular transformation based on the design of novel monomolecular environment, (2)molecular transformation based on the design of novel multimolecular environment, (3)molecular transformation based on the design of novel biological model system, and(4)theoretical consideration of the design of novel molecular environment. Group 1 studied the reactions of alpha-oxoamides, . acetylenes, cyclohexenone, tropothione in liquid crystals or crystals, and revealed the possible unique reactions in ordered systems like liquid crystals or crystals. Group 2 studied multipoint interaction in porphyrin derivatives, photosynthesis and visual system model, and epoxidation as an oxygenase model. Group 3 studied the reactions of carbenes or active oxygen species in cryogenic matrices, unique trifluoromethylation by electrolysis, the design of extremely bulky substituent as a unique molecular environment, and, chiral catalyst by BINAP-RU complexes. These results suggest that well-designed monomolecular systems can provide unique molecular environment. Group 4 studied the improvement of X-ray crystallographic analysis system, thus enabling very fact measurement of cystallographic data for crystalline phase reactions. Theoretical studies on some silicon clusters like Si_<60>, Si_<24>, Si_<6O>H_<60> were carried out to reveal interesting differences between the silicon and carbon clusters.
