understand and predict reactivity is highly important for the development of new reactions. In the context of Ni-catalyzed C(sp3)-O functionalization, we have developed a unique strategy employing activated cyclopropanols to aid the design and optimization of a redox-active leavinggroup for C(sp3)-O arylation. In this chemistry, the cyclopropane ring acts as a reporter of leaving-group reactivity, since the

Herein, we describe a protocol for the ring-opening arylation of 1-arylcyclopropyl tosylates, in which boronic acids promote ring-opening and a Ni catalyst facilitates arylation in high regioselectivity. A number of 2-arylated allyl derivatives are synthesized, which are relevant motifs found in biologically active molecules.

isomerization of 1-(1'-cycloalkenyl)cyclopropyl sulfonates under mild conditions. The remarkable ease of ringopening is attributed to the presence of a 1'-alkyl substituent. Also included is a palladium-catalyzed ringopening reaction of 1-(1'-cycloalkenyl)cyclopropyl tosylates for convenientpreparation of substituted 1,3-dienylamines, which complements previously reported nucleophilic substitution reactions
