Abstract

Procedimiento de síntesis de mercaptanos, por reacción fotoquímica de un compuesto etilénico con hidrógeno sulfurado, en presencia de un promotor constituido por un compuesto orgánico de un elemento del grupo V A de la Clasificación periódica de los Elementos, caracterizado porque el medio de reacción contiene además una benzofenona o/y una tiobenzofenona, pudiendo estos adyuvantes llevar unos sustituyentes en uno o los dos núcleos bencénicos.
