A direct dehydrogenative amidation reaction of aldehydes and amines under a visiblelightmediated ligand-to-metal charge transfer (LMCT) process was described. In this protocol, aldehyde substrates were activated by photoinduced hydrogenatomabstraction (HAA), generating acyl chloride intermediates followed by nucleophilic addition of amines. The synthetic method furnishes good functional group tolerance
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.
