Aldol reaction A carbon–carbon bond‑forming reaction between carbonyl compounds that produces β‑hydroxy carbonyls or α,β‑unsaturated carbonyls; widely used in synthesis and stereocontrol.
Grignard reaction — organomagnesium additions for carbon–carbon bond formation Grignard reaction A widely used organometallic method in organic synthesis: formation of organomagnesium reagents that add to electrophilic carbon centers to create C–C and C–heteroatom bonds.
