The mechanism of the formose reaction catalyzed by thiazolium salt was investigated by MOPAC-PM3 semi-empirical molecular orbital (MO) method in order to elucidate the factor(s) stabilizing the reaction intermediates. We assumed that one factor was t

We quantitatively studied the effects of counter anions and solvents on the catalytic activity of thiazolium due to the completion of the formose reaction using the highly active immobilized catalyst. The relation between counter anions and the catal

The dependence of the fluorescence lifetime of the 4S3/2 state of the Er3+ ion on the ErF3 concentration was measured in fluorozirconate glasses at room temperature. Energy transfer rates were calculated from optical parameters assuming that the Er3+

Thiazolium ion catalyst was immobilized on a cation-exchange resin, and the formose reaction was carried out with the resin. As a result, the use of this resin turned out to be useful for the formose reaction in an organic solvent, similar to the fre
