DMF and DMSO catalyse the reaction of butanol with PhNCO but inhibit that with aliphatic isocyanates, due to formation of an active 1 : 1 charge transfer complex with the aromatic isocyanate. Similarity was found in the mode of catalysis of the urethane reaction with these solvents to that with tert
Evidence is presented for selectivity in the reaction of metaphosphate, W I -, with methanol in preference to t-butanol in acetonitrile solution. In dichloromethane so ution there is also evidence for preferential nucleophilic solvation of reactant by methanol vs. t-butanol. - Following the direct
