This gel was used as catalyst in synthesis of various formanilide and thiocarbamate derivatives. Among synthesized compounds representative compounds were characterized by spectral studies. Such co-polymer gel is reused for several cycles with constant efficiency. KEYWORDS: Acryl amide, 1,1,3,3-tetra methylguanidine acrylate, Bisacrylamide, Co-polymer gel I. INTRODUCTION For the perspective of organic chemist, the relevance of polymer has changed and evolved dramatically over past half century. From their early use in peptide and oligosaccharide synthesis 1 to more recent preparation of small organic molecule libraries 2 , polymers have been used to aid in reaction manipulation and product isolation. Polyfunctionalized polymers have recently gained great practical importance because of their industrial applications 3,4 . Non-conventional catalyst like polystyrene is noncorrosive and easy to separate from reaction mixture. They can also be used repeatedly over prolonged period without any difficulty in their handling and storage 5 . Some polymer catalysts are applicable for various organic conversions 6 . Polymers with attached transition-metal complexes have recently been developed to catalyze hydrogenation, hydroformylation of olefins and carbonylation of methanol 7 . One of the most useful and versatile functional groups to be introduced in an organic molecule is formyl group. Formamides are widely used in organic synthesis as protecting group of amines 8 , precursor for isocyanide preparation 9 . In addition they have been used in synthesis of formamidines 10 . Acetic formic anhydride 11 continues to be most widely used formylating reagent but it is sensitive to atmospheric moisture. Recently polyethylene glycol has been reported as medium for formylation of aniline derivatives with formic acid 12 . Esters belong to wide range of category ranging from aliphatic to aromatic with various substitutions and multifunctional groups 13 . Esterification is industrially important reaction producing organic esters at the level of tones per year. Various ionic liquids were immobilized on polystyrene using different coupling agents and showed high activities for expeditious synthesis of homoallylic alcohols and esterification 14 . Due to variety of applicability of co-polymer gel in the field of organic synthesis, we prompted us to study the catalytic usabilities of co-polymer gel. II .RELATED WORK Literature survey reveals that various methods have been reported for N-formylation of amines. Acetic formic anhydride, chloral 15 , ammonium formate 16 , aq. 85% formic acid & ZnO 17 , activated formic acid using DCC 9 or EDCI 18 . However these methods have several drawbacks like delayed reaction times, elevated temperature, use of toxic formylating agents &
