Reactions of dimethyl 2-chloroethynylphosphonate with 1-substituted 5-oxo-1H-1,2,3,4-tetrazoles

Addition of 1-substituted tetrazol-5-ones to dimethyl 2-chloroethynylphosphonate occurred regioselectively to form new geminally substituted bis(4-R-5-oxo-4,5-dihydro-1H-tetrazol-1-yl)ethenylphosphonates with 65- 92% yield.
