The synthesis and characterization of organometallic polysulfanes and polyselenanes of titanium (IV), zirconium (IV), and hafnium (IV) /McCall, James M. January 1983 (has links)
The complexes Cp(,2)M(SH)(,2), where M = Ti and Zr, have been prepared and treated with S(,8) and >N-S(,x)-NN = benzimidazolyl, phthalimidyl and x = 1, 2, to give the metallacyclohexasulfanes Cp(,2)MS(,5). Reaction of Cp(,2)TI(SH)(,2) with >N-SR, where >N = phthalimidyl, succinimidyl, gave the complexes Cp(,2)Ti(S(,2)R)(,2) (R = CHMe(,2)) and Cp(,2)Ti(SR)(S(,3)R) (R = Ph, 4-C(,6)H(,4)Me). The thiolates Cp(,2)Ti(Cl)SR and Cp(,2)Ti(SR)(,2) (R = CHMe(,2), CMe(,3), Ph, 4-C(,6)H(,4)Me) were prepared for comparison. Treatment of the complexes Cp(,2)MCl(,2) with anhydrous solutions of Li(,2)E(,x) gave the complexes Cp(,2)ME(,5), where M = Ti, Zr, Hf and E = S, Se. The compounds (RCp)(,2)TiS(,5) (R = Me, SiMe(,3)),CH(,2)Cp(,2)TiS(,5), and (Me(,5)Cp)CpTiS(,5) were prepared similarly. Reaction of Li(,2)S(,x) with (Me(,5)Cp)(,2)MCl(,2) gave the metallacyclotetrasulfanes (Me(,5)Cp)(,2)MS(,3). The complex Cp(,2)Ti{S(CH(,2))(,3)S} was synthesized. Variable temperature ('1)H NMR studies established the barriers ((DELTA)G('(NOT=))) for ME(,x) and TiS(,2)C(,3) ring reversal in the above complexes. The crystal structures of Cp(,2)Ti(SPh)(S(,3)Ph), Cp(,2)MS(,5), and (Me(,5)Cp)(,2)TiS(,3) are discussed.

Arene chromium tricarbonyl complexes in synthesisCoote, S. J. January 1989 (has links)
The last chapter describes an extension of this cyclisation reaction enabling the synthesis of homochiral l-aryl-l,2,4,5-tetrahydrobenzazepines. The stereoselectivity observed in the acid-mediated cyclisation of homochiral N-(3,4-dimethoxyphenethyl)halostachine to Nmethyl- l-phenyl-l,2,4,5-tetrahydrobenzazepine is assessed. The chromium tricarbonyl complex of this cyclisation precursor undergoes a stereoselective cyclisation to furnish the homochiral 1-aryl benzazepine after decomplexation. The diastereoselectivity observed in the acid-mediated cyclisation of homochiral N-3,4-dimethoxyphenethyl phenylpropanolamines is also investigated and the mechanism by which they occur is discussed. Coordination of one of these precursors to the chromium tricarbonyl unit renders the cyclisation stereoselective to give homochiral N-methyl-1 -phenyl-2-methyl-7,8-dimethoxy-1,2,4,5-tetrahydrobenzazepine after decomplexation.
