Ford, David W. Ryba, and Simon T. Belt Department of Chemistry, University of California, Santa Barbara, CA In this chapter, we describe flash photolysis experiments using time-resolved infrared (TRIR) detection techniques to probe the reactivities of key intermediates proposed for the mechanisms of the thermal migratory insertion of CO into a metal-alkyl bond. The intermediates studied were generated by the photodissociation of CO from the metal complexes CpFe(CO)L(COCH ) (Cp is η -C H , L is CO or phosphine) and Mn(CO) (COCH ). Kinetic and spectroscopic evidence points to the formation of a solvated species in each case, which undergoes migration of the acyl methyl group to the metal center, competitive with trapping by addition of a ligand. In cyclohexane, the CpFe intermediate CpFe(CO)(sol)(COCH ) (sol is solvent) undergoes methyl migra tion at a rate (k = 5.6 x 1Ο M s ) several orders of magni tude faster than does the remarkably slow manganese analog (k = 6.0 M s ). Comparisons are also made to the reactivity of the unsaturated intermediate Mn(CO) (sol)(CH ) formed by CO photodissociation from Mn(CO) (CH ). -A T H O R O U G H U N D E R S T A N D I N G O F T H E MECHANISMS of the photoreactions of organometallic compounds requires far more than the measurements of quantum yields and the determinations of photoproduct © 1993 American Chemical Society In Photosensitive Metal—Organic Systems; Kutal, C., et al.; Advances in Chemistry; American Chemical Society: Washington, DC, 1993.","PeriodicalId":245674,"journal":{"name":"Advances in chemistry series","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129926488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
