20: R = Et; L = 4-L6; L6 = cyclopenta[2,1-b:3,4-b′]dithiophenyl}, were prepared by treating TiCl4 with the dilithium salts generated by reaction of the corresponding ligands (3, 4, 7, 8, and 11−15) with nBuLi in the presence of Et3N in toluene. In the ligand synthesis, the use of L2-H afforded R2Si(L-H)[2-(OCH2CH═CH2)-3-tBu-5-Me-C6H2] (7a: R = Me; L = 4-L2, 8a: R = Et; L = 4-L2) along with a small
