✦ Synopsis

A convenient synthesis of 4-ethynylpyridine, 5, starting from 4-vinylpyridine has been developed. Compound 5 reacts readily with pyridyl-and aryl-iodides to give the linear bidentate ligands 7, 9, and 11 in excellent yields.

A polymer-supported distannane 1 was prepared by treatment of tin halide resin with lithium naphthalenide or sodium naphthalenide in THF. The content of the polymers 1 was determined to be 0.95 to 1.13 mmol/g tin as ditin. The polymer-supported distannane reagent was successfully applied to radical
