Abstract A simple and convenient method for the synthesis of thiophosphates by coupling of phosphites with thiols under mild conditions has been developed. The reactions were promoted by trichloroisocyanuricacid (TCCA) and were carried out at room temperature in a one-pot two-step procedure within 20 min. A variety of substrates was tolerated in this method. Notably, both aryl and alkyl thiols could

A new class of chemical compounds useful for the control of insects consists of (methyl) (arylsulfenyl)-carbamic acid esters of 2,3-dihydro-2,2-dimethyl-7-benzofuranol. The preparation of these compounds, their physical properties, formulation, and use to control both household insects and crop insects are exemplified.
A microbicide having the general formula ##STR1## wherein R is a halomethyl radical, or a methylene radical; W is cyclohexyl, phenyl or meta or para substituted phenyl wherein the substituents are C.sub.1 -C.sub.4 alkyl, halogen or nitro; X and Y is hydrogen, C.sub.1 -C.sub.4 alkyl, halogen or nitro; provided that when R is halomethyl n is 1 and when R is methylene n is 0.
