This invention provides an antigen-free and immunologically inert tissue graft material and methods of preparing and using these tissue graft materials.

Biocompatible tissue graft material for implant and method of making

Described are preferred processes for preparing 3,5-dichloropyridines by dechlorinating higher-chlorinated pyridine compounds such as 2,3,5,6-tetrachloropyridine in an acidic medium in the presence of zinc and optionally a quaternary ammonium catalyst.

Dechlorination of pyridines in acidic, zinc-containing mediums

Described are preferred processes for dechlorinating chlorinated pyridine compounds in the presence of zinc, an alkaline reagent and a phase transfer catalyst. Particularly preferred processes provide advantageous synthetic routes to 2,3,5-trichloropyridine starting with 2,3,5,6-tetrachloropyridine.
