METAL MERCAPTIDES. PART I. TITANIUM TETRAMERCAPTIDES AND DIALKYLAMINOTITANIUM(IV) MERCAPTIDES.
Abstract
Reactions of excess mercaptan R'SH (R' = Me, Et, or ISO-Pr) with titanium dialkylamides Ti(NR2)4 (R = Me or Et) gave insoluble non-volatile red titanium tetramercaptides containing strongly addended mercaptan and amine, viz. Ti(SR')4, (R'SH)x(R2NH)y. It is suggested that these compounds are polymeric due to mercaptide bridges and that 8-coordinated titanium may be involved. Soluble complexes of the type Ti(SR')4, (R2NH)x, where R' = n-Pr or n-Bune, were also obtained. Attempts to prepare titanium tetratert.-butylmercaptide gave products believed to be titanium sulphide tert.-butylmercaptides which on heating gave impure titanium sulphide. Controlled addition of ethylmercaptan or isopropylmercaptan to Ti(NR2)4 gave soluble compounds: Ti(NMe2)3SEt, Ti(NMe2)2(SEt)2, Ti(NMe2)3Siso-Pr and Ti(NMe2)2(Siso-Pr)2 which were shown by cryoscopic measurements to be polymeric. Infrared and n.m.r. spectra were also obtained. (Author)
