Steric Effects in Reactions of Decamethyltitanocene Hydride with Internal Alkynes, Conjugated Diynes, and Conjugated Dienes
Original language description
New titanocene dihydrosulfide compounds [(C5Me4CH2Ph)(2)Ti(SH)(2)] (6) and [(C(5)Me(4)t-Bu)(2)Ti(SH)(2)] (7) were obtained by addition of hydrogen sulfide to the corresponding doubly tucked-in titanocenes, and titanocene hydrosulfide compounds [(C5Me4CH2Ph)(2)TiSH] (8) and [(C(5)Me(4)t-Bu)(2)TiSH] (9) by H2S-induced protonolysis of sigma-Ti-C bonds in [(eta(5)-C5Me4CH2Ph)Ti(III)(eta(5):eta(1)-C5Me4CH2-o-C6H4)] and [(C(5)Me(4)t-Bu)Ti(III)(eta(5):eta(1)-C5Me4CMe2CH2)], respectively. The crystal structuresof 6, 8, and 9 and electronic absorption spectra of 6-9 in hexane solution highly resemble those of corresponding [Cp-2*Ti(SH)(2)] (1) and [Cp-2*TiSH] (2), however, compounds 6 and 7 strongly differ in their sensitivity to sunlight mutually and with respect to 1. The sunlight photolysis of 6 in toluene proceeded similarly to the process described previously for 1 except that about three times longer exposition (300 h) was required to obtain the cyclopentadienyltitanium sulfide cage clus
