Paramagnetic alkyl, hydride, and alkene complexes of the Tp{sup t-Bu,Me}Co moiety
- Univ. of Delaware, Newark, DE (United States). Dept.of Chemistry and Biochemistry
The paramagnetic 15-electron alkyls Tp{sup t-Bu,Me}Co(R) (R = Me, Et, n-Bu) have been prepared, and the closely related Tp{sup t-Bu}Co(Me) has been structurally characterized. Hydrogenation of Tp{sup 5-Bu,Me}Co(N{sub 2}) produced the analogous hydride, Tp{sup t-Bu,Me}Co(H), the crystal structure of which has been determined. Reactions of Tp{sup t-Bu,Me}Co(N{sub 2}) with ethylene and propene yielded the corresponding olefin complexes Tp{sup t-Bu,Me}Co(C{sub 2}H{sub 3}R) (R = H, Me). Tp{sup t-Bu,Me}Co(C{sub 2}H{sub 4}) has been structurally characterized by X-ray diffraction as well. The alkyls are thermally stable and show no tendency to {beta}-eliminate; upon exposure to CO homolytic cleavage of the Co-C bond is observed rather than migratory insertion.
