In comparison to the extensively studied metal-catalyzed hydroamination reaction, hydroaminomethylation has received significantly less attention despite its considerable potential to streamline amine synthesis. State-of-the-art protocols for hydroaminomethylation of alkenes rely largely on transition-metal catalysis, enabling this transformation only under highly designed and controlled conditions. Here we report a broadly applicable, acid-mediated approach to the hydroaminomethylation of unactivated alkenes and alkynes. This methodology employs cheap, readily available, and bench-stable reactants and affords the desired amines with excellent functional group tolerance and impeccable regioselectivity. The broad scope of this transformation, as well as mechanistic investigations and in situ domino functionalization reactions are reported.

New immonium trifluoroacetates 1 and 2 react readily with functionalized organozinc or magnesium reagents leading to the corresponding aminomethylated products of type 5 and 7. The resulting bis-allylamines were deallylated leading to primary amines.
Elective herbicide compositions having a prolonged action containing α

, (2008/06/13)
The invention relates to compositions useful for prolonging the action and increasing the selectivity of herbicide compositions containing α-chloroacetamide derivatives as active ingredient as well as to highly selective herbicide compositions containing α-chloroacetamide derivatives as active ingredients and optionally an antidote wherein an animal derivative of the general formula (III) is used for achieving the prolonged action and increased selectivity. In the formula (III) STR1 R5, R6, R7 and R8 stand independently for hydrogen, a C1-6 alkyl, C3-7 cycloalkyl or C2-5 alkenyl group optionally substituted by a C1-4 alkyl group; and R9 stands for hydrogen or a C1-4 alkyl group optionally substituted by halogen, or a phenyl group.
Composition for prolonging the action of herbicides and herbicide compositions with a prolonged action
-
, (2008/06/13)
The invention relates to compositions (extenders) useful for prolonging the action of herbicides containing thiolcarbamate derivatives as active ingredients as well as to herbicide compositions with a prolonged action containing thiolcarbamate derivatives as active ingredients and optionally an antidote which comprises a diaminomethane derivative of the general formula (III) STR1 wherein the R substituents stand independently from one another for C1-6 alkyl groups or for C2-4 alkenyl groups optionally substituted by a C1-4 aklyl group; and a process for prolonging the action of herbicide compositions containing a thiolcarbamate derivative and optionally an antidote, which comprises applying the above mentioned composition in a quantity providing the prolonged action simultaneously with or after the application of the herbicide composition.
