Process for preparation of iodopropargyl carbamates

Abstract

A Process for producing N-alkyl iodopropargyl carbamate comprising: A. reacting a dialkyl(C.sub.1 -C.sub.3) carbonate with propargyl alcohol in the presence of a first catalyst under conditions to produce dipropargyl carbonate; B. reacting said dipropargyl carbonate with an alkyl(C.sub.1 -C.sub.6)amine, optionally in the presence of a second catalyst, to produce N-alkyl(C.sub.1 -C.sub.6) propargyl carbamate; C. reacting said N-alkyl(C.sub.1 -C.sub.6) propargyl carbamate with an iodinating agent to produce N-alkyl(C.sub.1 -C.sub.6) iodopropargyl carbamate is disclosed.
