Abstract

The reaction of α‐naphthylacetic acid (1) (a plant growth stimulator) with 4,5‐epoxy‐4‐methyloctane (2) which reproduces the constitutional unit of epoxidized 1,4‐polyisoprene was studied. The rate of addition of the acid to the oxirane ring of 2 in chloroform with the tetramethylammonium salt of the acid 1 as catalyst increases with temperature, time, and concentration of the reagents.

The addition of benzoic acid to the oxirane ring of epoxidized polymers of dienes is limited by side reactions which are promoted by increase of time, temperature, or epoxide concentration. Only high [Acid]/[Epoxide] ratios afford good yields of modification of the epoxidized polymers. a) Partie I:

## Abstract Lysine, as cupric complex, was fixed by its ε‐NH~2~ end group onto pentamethylene or 3‐oxapentamethylene dichloroformates, and to sebacoyl dichloride. Copper elimination yields dicarbamates and diamides which can be used as prepolymers or as crosslinking agents.
