    Abstract: The invention relates to a method for producing carbonyl compounds of formula (I), in which R is a hydrogen atom or alkyl radical with between 1 and 3 C atoms; R is a hydrogen atom or a radical of formula (II), in which R is a hydrogen atom or, together with R , an oxygen atom; R is the radical OR or, together with R , an oxygen atom; R is a hydrogen atom, an alkyl radical with between 1 and 8 C atoms or a cyclohexyl or cyclopentyl radical; and R is an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH2-CHO or -CH2-CH2-O-CH2-CHO. According to said method, the carbonyl compounds are produced by gas phase oxidation of methanol or alcohols of formula (III), in which R and R have the meaning assigned above and R is a hydrogen atom or an OR radical, and R is a hydrogen atom, an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH2-CH2-OH or -CH2-CH2-O-CH2-CH2-OH, with a gas containing oxygen, in the presence of catalysts containing copper and/or silver, and a phosphorus compound which is volatile under reaction conditions in such a quantity that the amount of phosphorus (calculated as P), in relation to the part by weight of alcohol used, is up to 20 ppm. Said method is characterized in that the quantity of phosphorus is added in at least two parts: a) the first part is added with the gaseous starting mixture before the catalyst bed, and b) at least one other part is added in the catalyst bed.

    Abstract: Prodn. of chlorothioformate esters of formula R-S-CO-Cl (I) is effected by reacting a thiol of formula R-SH (II) with CoCl2 in the presence of a catalytic amt. of a cyclic tert. amine (III), where R = an organic gp. (III) is a mono- or dialkylated 5- or 6-membered aromatic or nonaromatic heterocyclic cpd. contg. 1 or 2 tert. N atoms, where the alkyl gps. contain a total of 5-20 C atoms.
