Reaction of Dimethyl Chloroacetylenephosphonate with 1-Methyl-5-thio-1,2,3,4-tetrazole

摘要

We have recently shown that the reaction of dimethyl chloroacetylenephosphonate with 4-amino-5-mcthyl-3-thio-l,2,4-triazole proceeds with a high chemo- and regioselectivity to afford the corresponding phosphorylated thiazolotriazolium chloride [1].
