摘要:
New pesticidal e.g. insecticidal, compounds are of formula ##STR1## wherein X represents hydrogen, halogeno or an alkyl group, Z represents hydrogen, an alkyl group or a cyano or ethynyl group and R represents the residue of a carboxylic acid RCOOH which is an acid forming a pesticidal compound when esterified with .alpha.-cyano-3-phenoxybenzyl alcohol.The compounds can be prepared by conventional methods e.g. esterification.
摘要:
A 24,25-dihydroxycholestane derivatives of the formula ##STR1## wherein A is a steroid residue and R is an aryl group and a process for preparation of the same are disclosed. The derivatives are an intermediate for synthesis of 24,25-dihydroxycholecalciferol having useful physicological activity like that of vitamin D.sub.3. 24,25-Dihydroxycholecalciferol can be produced in an industrially advantageous method via the intermediate which is easily prepared from commercially available starting compounds.

摘要:
A tertiary amine and an alcohol are transalkylated. The tertiary amine is reacted with the alcohol, or with the formate ester of the alochol, at a temperature of from about 50.degree. to 300.degree. C. When the reaction is effected using the alcohol (rather than its formate ester), then the reaction is carried out in the presence of carbon monoxide.
