摘要:
Polysubstituted .alpha.-aminoacetamides of the formula ##STR1## wherein R.sup.1 is tert-alkyl; R.sup.4 is alkyl, phenyl, substituted phenyl, cycloalkyl, piperidinyl, tetraalkylpiperidinyl or an alkylene (.alpha.-aminoacetamide). These compounds are prepared by first reacting an .alpha.-haloacetamide with a base to form an .alpha.-lactam intermediate which in turn is reacted with a primary amine. The compounds are useful as stabilizers of polymeric materials against ultraviolet light degradation.
摘要:
Herbicidal-substituted .alpha.-(trimethylcycloalkenyl)-N-alkylacetamides of the formula ##STR1## wherein R is a linear or branched alkyl or alkoxyalkyl radical with 1-6 carbon atoms or an allyl radical, optionally substituted with C.sub.1 -C.sub.4 alkylene groups, and X is a substituent from the group consisting of hydrogen, methyl, chlorine and bromine, in any combination, the free valences signify hydrogen and two of the methyl groups on the ring are attached to the same carbon atom, are useful pre- and post-emergent herbicides for weed control in crops.
