ADDITION OF H2S TO TERPENES FOR PRODUCING NOVEL MOLAR MASS REGULATORS FOR RADICAL POLYMERISATIONS

The present invention relates to a method for producing thiols through addition of hydrogen sulfide onto at least one unsaturated terpene, where the reaction is carried out in the presence of at least one organic ion exchanger, and to the use of thiols derived from terpinolene as molar mass regulator in the polymerization of monomers.

Simple synthetic protocols for tertiary alkyl and allyl thiols

Convenient preparative methods for tertiary alkyl and allyl thiols are described. Accordingly, thiolesters and thiocyanates, obtained from the reaction of SN1-active halides and appropriate zinc salts, on hydrolysis and LAH reduction respectively, afford the corresponding thiols in near quantitative yields. Besides the well known p-menth-1-ene-8-thiol, p-menthane-1-thiol, p-mentha-1,8-diene-6-thiol and 2-(2-phenyl)propane thiol have been prepared.

ELECTROPHILIC THIYLATION OF BICYCLIC MONOTERPENES BY HYDROGEN SULFIDE AND 1-BUTANETHIOL

The thiylation of α,β-pinenes and camphene by hydrogen sulfide and 1-butanethiol, catalyzed by aluminum halides and alkylaluminum halides, was investigated.The regioselectivity and stereoselectivity of the reaction depend on the acidity of the catalyst.The thiylation of pinenes by hydrogen sulfide in the presence of alkylaluminum halides leads to the preferential formation of trans-pinane-2-thiol, and the catalyst with the higher acidity (aluminum bromide) promotes the menthene isomerization of the pinenes.
