title: Synthesis of dialkyl 2,5-dihydro-5-oxo-1,2-azaphosphole-3,4-dicarboxylates.
abstract: The adducts produced in the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates were trapped by arylsulfonyl isocyanates to produce dialkyl 2,5-dihydro-5-oxo-1,2-azaphosphole-3,4-dicarboxylates in good yields.
