The reactions of mono(cyclopentadienyl)titanium(IV) trichloride with three important series of heterocyclic thioketones, <I>viz.</I>, triazolinethiones 4-amino-, 4-benzylideneamino-, 4-furfurylideneamino-, and 4-salicylideneamino-5-trifluoromethyl-1,2,4-triazoline-3-thiones, thioxoquinazolones (3-methyl-, 3-phenyl-, and 3-(<I>o</I>-tolyl)-2-thioxo-4-quinazolones), and oxadiazolethiones (5-phenyl-, 5-(<I>p</I>-nitrophenyl), and 5-(<I>p</I>-chlorophenyl)-1,3,4-oxadiazole-2-thiones, have been studied in anhydrous dichloromethane. The reaction products have been characterized on the basis of elemental analyses, electrical conductance, magnetic susceptibility and spectral (electronic, infrared, and <SUP>1</SUP>H NMR) data. Proton NMR spectra indicate that there is rapid rotation of the cyclopentadienyl ring around the metal ring axis on the NMR time scale at 28 °C.
