Biologically active heterobicyclic hydroximidates and

A novel and efficient method for preparing S-chloromethyl derivatives of O-alkylphosphorodithioic acids involves reacting the S-hydroxymethyl derivative of such an acid under substantially anhydrous conditions with a suitable acid chloride in a chemically unreactive organic liquid which is a solvent for both said S-hydroxymethyl derivative and said acid chloride. Suitable acid chlorides are PCl.sub.5, PCl.sub.3, acetyl chloride, chlorinated derivatives of acetyl chloride, oxyalyl chloride, phosgene, thionyl chloride, sulfuryl chloride, aryl sulfonyl chlorides and chloro- or nitro-substituted aryl sulfonyl chlorides.

Preparation of S-chloromethylated O-alkyl substituted phosphodithioic

An economical process for the controlled S-chloromethylation of O-alkyl esters of dithiophospho acid compounds with methylene chloride is provided by conducting the reaction in a liquid medium comprising a large excess of methylene chloride and a substantial, reaction promoting proportion of a highly polar, miscible, organic cosolvent.

Process for S-chloromethylation of organic dithiophospho compounds with

This is a novel process for the preparation of m-phenoxybenzaldehyde, a useful and valuable intermediate for the synthesis of pyrethroid type pesticides. The process comprises halogenation of m-phenoxytoluene on the side chain, in an inert solvent and in the presence of free radical initiators or strong light to a mixture of the corresponding mono and dihalo derivatives, and conversion of the mixture to m-phenoxybenzaldehyde by a Sommelet-type reaction.

Process for the preparation of m-phenoxybenzaldehyde

Certain derivatives of cyclopropane carboxylic acid and their esters are useful and valuable intermediates for the preparation of broad spectrum pyrethroid type pesticides. The invention provides a novel method for the preparation of the derivatives of cyclopropane carboxylic acid and esters from stable sulfonium ylides.

Process for the preparation of cyclopropane carboxylic acids and esters

The invention is novel hydrocarbon ethers of aminophenol derivatives, and their use in preventing the proliferation of insects by interfering with their normal development and growth pattern.

Insect control compounds

This disclosure describes esters of dithioimidocarbonic acid having chemosterilant and larvicidal activity.

Chemosterilant and larvicidal imidothiocarbonates

This invention relates to a novel process for the preparation of 4-chloro-2-alkylphenylisocyanide dichlorides. More particularly, this invention relates to the chlorination of ortho substituted phenylisocyanide dichlorides exclusively in the para-position. The compounds are useful intermediates in the preparation of ixodicidal, insecticidal, ovicidal and chemosterilizing agents.
