Catalytic transition metal compound with alkenes, alkynes and carbon monoxide, and other unsaturated molecules which can form complexes, so that the activation of these molecules, generating new compounds. E.g. hydrogen formaldehyde reaction of olefins, the olefin with hydrogen and carbon monoxide according to the mechanism of the formation of complexes of cobalt catalyst, the resulting aldehyde (R is an alkyl group): RCH = CH2 + CO + H2─ → RCH2CH2CHO some of the metal catalyst may be an olefin into multimers. For example, titanium (Ⅲ) chloride and alkyl aluminum complex, the PCE as a catalyst, can directed polymerization of olefins into polymers. 9 Bibliography edit Dai Anbang editor: "Coordination Chemistry" (Inorganic Chemistry Series) wholesale high quality tetrachlorethylene, Science Press, Beijing, 1987.
