Abstract:
A method for converting a substrate to an organohalide, comprising the steps of:a. forming a mixture comprising the substrate, a halogenating agent, and one or more catalysts of the formula: ##STR9##wherein R.sup.1 and R.sup.2 are independently selected fromi. unsubstituted or substituted C.sub.12 -C.sub.30 alkyl, C.sub.12 -C.sub.30 alkenyl, C.sub.12 -C.sub.30 alkynyl, and joined groups; andii. unsubstituted or substituted aminoalkyl and polyaminoalkyl and aminoalkenyl and polyaminoalkenyl wherein two or more of the amino groups are in the form of formamides;wherein the substituents are independently selected from any functional group which does not react with the substrate to be halogenated or the halogenating agent; andwherein the substrate is selected from the group consisting of carboxylic acids, aldehydes, amides, alcohols, N-heterocyclic compounds, phenols, heterocyclic thiols, and sulfonic acids; andwherein the halogenating agent is independently selected from the group consisting of thionyl chloride, sulfuryl chloride, phosphorous trichloride, phosphorous pentachloride, phosphorous oxychloride, phosgene, oxalyl chloride, and phosgene substitutes such as do- or tri-phosgene, triphenylphosphine-chlorine complex, and their corresponding bromo analogs; andb. maintaining the mixture at a temperature wherein formation of the organohalide occurs at an acceptable rate.
