Process of preparing {60 -formyl sulfides and 2-hydrocarbyl-thioaldoximes therefrom

Abstract

Abstract AND OXIMATING THE Alpha -FORMYL SULFIDE TO FORM A 2HYDROCARBYLTHIOALDOXIME OF THE FORMULA WHEREIN X is defined as above, reacting in an aqueous medium the Alpha -haloaldehyde with a thiol salt of the formula R''''''SM, wherein R'''''' and M are defined as above, to form an Alpha formyl sulfide of the formula WHEREIN R'' and R'''' are defined as above, to form an Alpha haloaldehyde of the formula Also, 2-hydrocarbylthioaldoximes are prepared by oximating the above Alpha -formyl sulfides by reaction with a source of hydroxylamine. Additionally, 2-hydrocarbylthioaldoximes are prepared by a process which comprises halogenating an aldehyde having the formula WHEREIN R'' and R'''' independently are hydrogen, hydrocarbon radicals of 1 to 18 carbon atoms selected from the group consisting of alkyl, cycloalkyl, alkenyl, cycloalkenyl and aryl, or substituted hydrocarbon radicals of the above group, and X is a halogen selected from the group consisting of chlorine, bromine, and iodine, with a thiol salt of the formula R''''''SM, wherein R'''''' is a hydrocarbon radical of 1 to 18 carbon atoms selected from the group consisting of alkyl, cycloalkyl, alkenyl, cycloalkenyl and aryl or a substituted hydrocarbon radical of the above group; and M is an alkali or alkaline earth metal, thereby forming an Alpha -formyl sulfide of the formula An Alpha -formyl sulfide is prepared by a process which comprises reacting in an aqueous medium an Alpha -haloaldehyde of the formula
