Abstract
Reactions of excess of thiol R′SH (R′= Me, Et, or Pri) with titanium dialkylamides Ti(NR2)4(R = Me or Et) gave insoluble non-volatile red titanium tetramercaptides containing strongly addended thiol and amine, viz., Ti(SR′)4, (R′SH)x(R2NH)y. It is suggested that these compounds are polymeric owing to mercaptide bridges and that octaco-ordinated titanium may be involved. Controlled addition of ethanethiol or 1-methylethanethiol to Ti(NR2)4 gave soluble compounds: Ti(NMe2)3SEt, Ti(NMe2)2(SEt)2, Ti(NMe2)3SPri, and Ti(NMe2)2(SPri)2 which were shown by cryoscopic measurements to be polymeric. Infrared and n.m.r. spectra were also obttained. Reactions with other thiols gave products which could not be characterised.Keywords
