Process for preparing penems

The mono-methallyl ether of pyrocatechin of formula (I): ##STR1## is prepared by reacting pyrocatechin of formula (II): ##STR2## with a methallyl halide of formula (III): ##STR3## in a homogeneous dissolving medium, e.g., alcohols, aliphatic polyalcohols and monoethers thereof, or water, in the presence of an organic or inorganic base. The mono-methallyl ether of pyrocatechin is used as an intermediate for organic syntheses and, in particular for synthesizing the product of formula (IV); ##STR4## which is marketed under the tradename 'Carbofuran' and is a compound which is the active principle in soil insecticides of different overall compositions which are available on the market.

A process is disclosed for preparing N-methylcarbamate of methylthioacetaldoxime, characterized in that an aqueous suspension of methylthioacetaldoxime is additioned, in one step only, with gaseous phosgene and aqueous methylamine in the presence of an inorganic alkaline base substantially at room temperature and pressure. The product obtained, known commercially as 'Methomyl', is an important active principle in the field of insecticides.

Process for preparing N-methylcarbamate of methylthioacetaldoxime

A process is disclosed for the carboxylation of organic substrates or reactants containing at least one active hydrogen atom by reaction with CO.sub.2 and alkaline phenates in an organic medium, characterized in that the reaction is conducted in the presence of simple or substituted alkaline phenates in at least an aprotic medium which is at least a partial solvent for the phenate, and selected from the class consisting of cyclic ethers, aliphatic, cycloaliphatic and heterocyclic tertiary amines, and cyclic sulphones, and at temperatures between about 40.degree. and 60.degree. C. The alkaline phenate is selected from the class consisting of the Li, Na, K salts of the phenols of the general formula: ##STR1## WHEREIN R is hydrogen or an alkyl or an alkoxy group, linear or branched, having up to 20 carbon atoms, or a phenyl group, n varies from 1 to 5, and M is the alkali metal. The starting organic substrate or reactant is selected from the class consisting of ketones, esters, nitroparaffins and nitriles. The alkaline phenate may be prepared 'in situ' from the corresponding phenol and alkaline hydroxide with azeotropic elimination by means of solvent of the water thus formed.

Process for the carboxylation of organic substrates with carbon dioxide
