A new, metal‐free, radical‐mediated oxidative decarbonylative hydroalkylation of various alkynes with secondary and tertiary alkyl aldehydes using di‐tert‐butyl peroxide (DTBP) as oxidant is presented. This method enables the simultaneous formation of a CC bond and a CH bond through a sequence of decarbonylation, radical addition and protonation, and provides a straightforward route for transforming
