Catalyst-transfer polymerization where the propagation steps comprise cross-coupling reactions.
Examples: - Kumada catalyst-transfer cross-coupling polymerization (KCTP), where the propagation steps comprise metal-catalyzed cross-coupling reactions of a Grignard reagent with an organic halide. The process is also known as Grignard metathesis (GRIM) polymerization.
- Suzuki−Miyaura catalyst-transfer cross-coupling polymerization, where the propagation steps comprise Pd-catalyzed cross-coupling reactions between an organoboron compound and an organic halide. Named polymerization reactions are deprecated in IUPAC terminology.
