developed for reactions of malonates with styrene derivatives. The concept of this process lies in the photo-oxidation of catalytic amounts of the enolate to form reactive radicals that react with alkene double bonds under mild reaction conditions. This is an example of visible-light-activated C–C bond formation reactions of malonates with alkenes to realize high atom economy under very mild reaction conditions
methylene compounds has been developed. Aryl substituted alkenes and an aliphatic diene can be used as alkyl sources for these reactions, which proceed via polycyanoarene sensitized, photoinduced electron transfer pathways that are promoted using very mild conditions (ambient temperature, without noble metals and halogens, and with weak bases such as alkali metal carbonate). The reactions that comprise the

1,3-Carbocarbonation of donor-acceptor cyclopropanes (DACs) was achieved by employing Grignard reagents under copper catalysis, followed by the addition of carbon electrophiles. This method allowed the installation of both saturated and unsaturated carbon residues at both the electrophilic and nucleophilic sites.
