New dendrimers 3-[G‘1]−3-[G‘4] possessing from 6 to 48 N(CH2PPh2)2 terminal groups are described. The corresponding Pd, Pt, and Rh complexes [N(CH2PPh2)2MRR‘] y (y from 6 to 24; generations 1−3) [M = Pd:  R = R‘ = Cl, Br; R = Cl, R‘ = Me; R = Br, R‘ = Me; R = Cl, R‘ = COMe; R = Cl, R‘ = norbornyl-COMe. M = Pt:  R = R‘ = Br, Cl, Me; R = Br, R‘ = Me. M = Rh:  R, R‘ = acac] are prepared by reacting 3-[G‘1]−3-[G‘3] with the appropriate transition metal complexes.

Treatment of Cp2Ti(CO)2 (3) with the di‐ and polysulfanes 1,2,4‐(CH2)2S3, C4S6 (9), C,7H10S3 (11), 1,2,4,6‐(CH2)3S4 (16), C6H10S6(19), and S6 affords the titanocene chelate complexes Cp2TiS3(CH2)2 (8), (Cp2Ti)2C4S6 (10), Cp2TiS3C7H10 (13), Cp2TiS2C7H10 (14), Cp2TiS4(CH2)3 (17), Cp,2TiS6C6H6H10 (20), and Cp2TiS8 (23). 14 is also obtained from Cp2TiCl2 (1) and the geminal dithiol of norbornene. The analogous reaction with the dithiol of dicyclopentadiene yields Cp2TiS2C10H12 (15). In ligand transfer reactions, 8 reacts with SCl2 to give 1,2,3,5‐tetrathiane (25), 10 provides 9 on reaction with Cl2, 13 when treated with S2Cl2 affords C7H10S5 (12), 15 reacts with S2Cl2Cl2 to give C10H12S4. 17 and SCl2 yield 1,2,3,5,7‐pentathiepane (18), 20 is converted to C6H10S7 (22) on reaction with SCl2, and 23 yields S10 and 1,2,‐C6H4(SCl)2, respectively. With phosgene, thiophosgene, and thionyl chloride, compound 15 yields the corresponding dithiocarbonate 26, the trithiocarbonate 27 and the trisulfane 2‐oxide 28. The structure of 27 was determined by X‐ray crystallography.
