Abstract
Abstract Cis -1,3,5-cyclohexanetriol [C 6 H 9 (OH) 3 ] reacts with η 5 -(C 5 R 5 )TiCl 3 [R 5 = H 5 , Me 5 , (Me 3 Si)(H) 4 , 1,3-(Me 3 Si) 2 (H) 3 , (1,3-(t-Bu) 2 (H) 3 ] in the presence of three molar equivalents of triethylamine, affording substituted cyclopentadienyltitanium cis -1,3,5-cyclohexanetrialkoxide complexes with an adamantane-type structure. The complex η 5 -(C 5 Me 5 )Ti(O 3 C 6 H 9 ) is thermally stable to 220°C in the solid state, and a benzene solution of the complex η 5 -(1,3-t-Bu 2 C 5 H 3 )Ti(O 3 C 6 H 9 ) is stable to cleavage of the alkoxide ligand by three equivalents of H 2 O for more than 3 h. Attempts to cleave 1,3-t-Bu 2 C 5 H 4 from η 5 (1,3-t-Bu 2 C 5 H 3 )Ti(O 3 C 6 H 9 ) with electrophiles H + and Br 2 are reported.
