The present invention provides compounds of formula I wherein Q is Q1 or Q2; A1, A2, A3 and A4 are independently of each other C-H, C-R7, or nitrogen; R1 is C1-C8haloalkyl; R2 is aryl or aryl substituted by one to five R11, or heteroaryl or heteroaryl substituted by one to five R11; and R3, R4, R5, R6 and R7 are as defined in the claims. The invention also provides methods of controlling insects, acarines, nematodes or molluscs which methods comprise 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).

hydroformylation of internal alkenes. We report here on a new class of phosphabarrelene/rhodium catalysts 2 that display very high activity towards hydroformylation of internal alkenes with an unusually low tendency towards alkene isomerization. Preparation of new phosphabarrelene ligands, studies of their coordination properties, as well as results obtained in the rhodium-catalyzed hydroformylation of cyclic
