摘要:
An improved process for the conversion of allyl and methallyl chloride to sodium allyl and methallyl sulfonate, respectively, by reaction with aqueous sodium sulfite which comprises conducting the reaction at 33.degree.-70.degree. C. and 33.degree.-80.degree. C., respectively, while maintaining the pH at 7-11 throughout the reaction.
摘要:
This invention relates to new derivatives of dibenzocycloheptenes and to processes for making them. More particularly, the invention includes 5H-dibenzo[a,d]-cycloheptenes and 10,11-dihydro-5H-dibenzo[a,d]cycloheptenes which are substituted at their 5-carbon atom with an aminopropyl or an aminopropylidene radical. The amino entity may be either primary or secondary and if secondary, the substituent may be either a lower alkyl or alkenyl radical having up to 6 carbon atoms, cycloalkyl having up to 8 carbon atoms or an aralkyl radical. The dibenzocycloheptene nucleus may be further substituted. The invention also includes the intermediates used for obtaining these products. Also included are derivatives such as acyl derivatives which yield the active compound under physiological conditions.
摘要:
2-Trifluoromethylmethanesulfonanilides substituted in the para (four) position by phenylthio, phenylsulfinyl or phenylsulfonyl groups and agriculturally acceptable salts thereof and compositions containing these compounds are useful herbicides.
摘要:
The invention relates to new propionamidine derivatives of formula (I) ##STR1## wherein X is halogen,and to a process for their preparation. According to the invention compounds of the formula (I) are prepared by reacting a 3-halopropionitrile of the formula (III) ##STR2## wherein X is as defined above,with sulfamide of the formula (II) ##STR3## in the presence of a hydrogen halide. Compounds of the formula (I) are useful intermediates in the preparation of famotidine.
