leading to good yields, and mechanistic experiments were performed to elucidate the catalyst's possible mechanistic pathway. Moreover, the inherent selectivity challenge regarding α,α-disubstituted aldehydes (decarbonylation problem) was studied and addressed.

SelectiveC−Hactivation is an area of growing importance. Metal‐free C−Hactivation of branched aldehydes mediating the hydroacylation of electron‐deficient alkenes is an attractive transformation, but is limited by selectivity issues, especially in the case of α,α‐disubstituted aldehydes. Herein, we report a green, cheap, versatile, and easily reproducible selectivehydroacylation of alkenes utilizing
