Reactions of excess mercaptan RSH R Me, Et, or ISO-Pr with titanium dialkylamides TiNR24 R Me or Et gave insoluble non-volatile red titanium tetramercaptides containing strongly addended mercaptan and amine, viz. TiSR4, RSHxR2NHy. 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 TiSR4, R2NHx, 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 TiNR24 gave soluble compounds TiNMe23SEt, TiNMe22SEt2, TiNMe23Siso-Pr and TiNMe22Siso-Pr2 which were shown by cryoscopic measurements to be polymeric. Infrared and n.m.r. spectra were also obtained. Author
