The catalytic activity of Et3NHCl€"AlCl3 proved to be superior to that of other catalysts for the condensation of benzene and paraformaldehyde, giving 92.4% conversion of HCHO and 76.1% selectivity to diphenylmethane at 80 °C and atmospheric pressure. The effect of various reaction conditions on...
In this work, a similar approach to substituted cucurbituril synthesis is reported (Scheme 1), whereby one mole equivalent of monomethylglycoluril (1) was added to four mole equivalent of dimethylglycoluril (2) in 12 M HCl with the addition of formaldehyde to produce a mixture of methyl-...
