The catalytic enantioselective synthesis of α-chiral olefins represents a valuable strategy for rapid generation of structural diversity in divergent syntheses of complex targets. Herein, we report a protocol for the dual CuH- and Pd-catalyzed asymmetric Markovnikov hydroalkenylation of vinyl arenes and the anti-Markovnikov hydroalkenylation of unactivated olefins, in which readily available enol triflates
A method of combating and controlling insects, acarines, nematodes or molluscs which comprises applying to a pest, to a locus of a pest, or to a plant susceptible to attack by a pest an insecticidally, acaricidally, nematicidally or molluscicidally effective amount of a compound of formula (I), wherein R1 is R4, YR5 or ZR6; Y is CO or C=S; Z is S, S(O), SO2 or PO2; and A is an optionally substituted phenyl or an optionally substituted heteroaromatic ring, wherein R1 to R6 are defined organic groups; new compounds are also provided.
