Abstract
•New phosphonylation reagents were developed.•Benzotriazole surrogates showing higher stabilities than the chlorophosphates.•The 1H-benzo[d][1,2,3]triazol-1-yl-1-phosphonates were obtained in high yields.•Efficient phosphonylation of N-, O-, and S-nucleophiles in good yields.•Establish the structure of a conjugate by a single crystal X-ray structure study.
Benzotriazole surrogates showing higher stabilities than the corresponding chlorophosphates, allow phosphonylation of a variety of N-, O-, and S-nucleophiles in good yields.
