1,3-Dipolar cycloaddition of diazomethane to the triple bond of trialkylsilyl-, trialkylgermyl-, and trialkylstannylalkoxyacetylenes proceeds regioselectivity and is a convenient method for synthesis of the previously not described 3(5)-element-substituted 4-alkoxypyrazoles. When heated in methanol in the presence of an acid, 3(5)-silyl(germyl)-4-alkoxypyrazoles are slowly hydrolyzed with cleavage of the element-carbon bond.
