regarding the protonation stereochemistry of such carbanions. Ab initio calculations (6-31G*) have shown that as the nucleophile approaches the bicyclobutane, the bridgehead activating group moves inward toward an axial position. With a charge localizing group (CN and S(H)SO2) the carbanion remains pyramidal, whereas with C(H)O as an activating group, the carbanion is nearly planar. It is suggested therefore

palladium hydride enabled hydroalkenylation of strained molecules. This new mild protocol proceeds via a regio- and chemoselective hydropalladation step, followed by a photoinduced radical alkyl Heck reaction. This methodology represents a new reactivity mode for strained molecules and opens new avenues for photoinduced palladium catalysis. The reaction is compatible with a wide range of functional groups
