General description

Trimethyl orthobenzoate reacts with P-dimethylaminophosphonic acid bis(1-methylhydrazide) to yield 1,2,5,6-tetrahydro-1,5-dimethyl-6-(N,N-dimethylamino)-6-phenyl-1,2,4,5,6-tetrazaphosphorine-6-oxide.

Application

Trimethyl orthobenzoate was used in the preparation of 5-phenyl-4,6-dipyrrin and 2,3-orthoester derivatives of ethyl-1-thio-α-L-rhamnopyranoside.
