Azolides, 7. - Phosphonate and Phosphate Group Transfer with Pyrazolides

The tert-butylammonium α-diazophosphinates 7 add onto acceptor-substituted acetylenes 8 with formation of N-phosphorylpyrazoles: Primarily formed 3H-pyrazoles 9 undergo spontaneous sigmatropic shift of the anionic PO-group to yield 10. α-Diazophosph

SALTS OF α-DIAZO "PHOSPHORUS ACIDS" - STARTING COMPOUNDS FOR PHOSPHONATE AND PHOSPHATE TRANSFER REAGENTS

Pyrazoles bearing N-phosphonate and phosphate groups are well accessible from salts of α-diazo "phosphrus acids" and electron poor acetylenes.They are good phosphorylating reagents for protic nucleophiles.
