Abstract: A protocol for the catalytic nucleophilic activation of unactivated styrenes is reported, which enables the generation of a non-stabilized alkenyl anion equivalent as a transient intermediate. In the reaction, N-heterocyclic carbenes add across styrenes to… read more here.

Abstract: After seminal Tsuji-Trost reactions (palladium catalyzed allylation of nucleophiles via π-allyl intermediates as electrophiles), the idea of reversal reactivity of π-allyl intermediates (i.e. π-allyl as nucleophiles) has been stated since the eighties. Thanks to different… read more here.
