  日期：——

  A mechanistically unprecedented approach for the formation of tertiary amides from N,N-dialkylchlorothiophosphoramidates and aldehydes has been developed. The reaction occurred via the activation of aldehydes with N,N-dialkylchlorothiophosphoramidates followed by amidation with dialkylamine pendent of the same phosphoramidate.

  一种在机制上前所未有的方法已被开发，用于从N,N-二烷基氯硫膦酰胺和醛中形成三级酰胺。该反应通过N,N-二烷基氯硫膦酰胺对醛的活化发生，然后与相同膦酰胺的二烷基胺发生酰胺化反应。

  This invention relates to agrochemical compositions comprising a benzamide compound of formula (I) where R 1 is fluoro, methoxy or C 1-4 alkyl; R 2 and R 3 are each independently optionally substituted C 1-6 alkyl or optionally substituted C 2-6 alkenyl; or R 3 is hydrogen and R 3 is optionally substituted C 5-8 alkyl or optionally substituted C 4-6 alkenyl or optionally substituted benzyl; or R 2 and R 3 and the nitrogen atom to which they are both attached together form an optionally substituted 5-, 6- or 7-membered ring, which ring optionally contains at least one further heteroatom selected from O, N and S; to the use of those benzamide compounds as solvents; to certain novel compounds of formula (I); and to a process for preparing those novel compounds.
