A series of palladiumcatalysed three component cyclisation-carbonylation-anion capture processes involving aryl iodides, carbon monoxide (1 atm) and Sn(IV)R or B(III)R reagents are reported. The stereo- and regio-specific cascade processes furnish tetrasubstituted carbon centres and fused- and spirocyclic-rings in excellent yield.

enhance the scope of our cyclization–anion capture methodology, is introduced and exemplified by a wide variety of catalytic cyclization–carbonylation–anion capture processes employing hydride, organostannanes and NaBPh4 as anion capture agents. Mono- and bis-cyclization processes forming 5- and 6-membered rings are described, all of which employ CO at atmospheric pressure. Cyclocarboformylation processes
