Cycloadditions of 3-aryl-1,2,4,5-tetrazines 1a-o with ethynyltributyltin S occur with high regioselectivity to yield 3-aryl-5-tributylstannyl- pyridazines 9-23 in 71-95% yield. Moreover, the stannanes obtained could be utilized as starting materials for t

The cycloaddition of 3-phenyl-1,2,4,5-tetrazine (1) with the silylethyne 2a proceeds highly regioselectively to give 3-phenyl-5-(trimethylsilyl)pyridazine (3a).Similarly the reactions of 1 with the silylalkynes 2b - f, the silylalkynones 2g - i, and the s
