Abstract: Compounds characterized by the following formula: ##SPC1##Wherein R and R' can be selected from the group consisting of C.sub.1 to C.sub.15 hydrocarbyl, preferably C.sub.1 to C.sub.6 alkyl, C.sub.3 to C.sub.7 cycloalkyl, phenyl optionally substituted by chlorine, bromine, nitro, cyano, C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy or C.sub.1 to C.sub.6 alkylthio; R and R' may form together a carbocyclic ring of from 3 to 8 carbon atoms. In addition, R can also be hydrogen. R" can be a C.sub.1 to C.sub.6 alkyl group optionally substituted by chlorine, bromine or cyano; phenyl optionally substituted by chlorine, bromine or nitro, R"' can have the same definition as R" and can be in addition a C.sub.1 to C.sub.6 alkoxy, C.sub.1 to C.sub.4 alkylthio and phenoxy optionally substituted by chlorine, bromine or nitro; X can be oxygen or sulfur.These compounds have been found to possess pesticidal activity, particularly insecticidal, miticidal and nematocidal activity.

Abstract: A method for producing ethane, ethylene and dimethyl ether compounds, said method comprising the step of passing a mixture of CO and hydrogen over platinum supported on alumina at a temperature ranging from 100.degree.C. to 400.degree.C. and a pressure ranging from 1 to 100 atmospheres.
