Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with a functionalized N-substituted pyrrole to thereby introduce the functionalized N-substituted pyrrole at the terminal reactive polymer chain end(s). A method is also disclosed whereby the N-substituent may be derivatized to a basic amine containing functional group. Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is subsitituted at the 2 and 3 position of the N-substituted pyrrole.

Cycloalkano[α]pyrroles were obtained by reductive radical cycloaddition of 1-(2-iodoethyl)pyrrole and activated olefins or by cyclization of 1-(ω-iodoalkyl)pyrroles, through electroreduction of the iodides using nickel(II) complex as an electron-transfer catalyst.
