Abstract
Abstract This invention relates to halogen derivatives of alkynoxymethylamines and to uses thereof. The present invention may be ideally illustrated by the following equation: RN(CH.sub.2 OR'C.tbd.CH).sub.2 + 2NaOX → rn(ch.sub.2 or'c.tbd.cx).sub.2 + 2naOH where R is a substituted group, preferably hydrocarbon, such as alkyl, cycloalkyl, aryl, etc., R' is hydrocarbon, preferably alkylene, and where X is halogen.
