YCl3, SmCl3, and LuCl3 react with 2 equivalents of Na[C5H4CH2CH2SR] (R = Ph (2); Et (3)) yielding (PhSCH2CH2C5H 4)2LnCl (Ln = Y (4a), Sm (4b), Lu (4c)), and (EtSCH 2CH2C5H4)2LuCl (5), respectively. Methylation of 4a, 4c, and 5 with LiMe produces (PhSCH 2CH2C5H4)2LnMe (Ln = Y (6a); Lu (6c)) and (EtSCH2CH2C5H 4)2LuMe (7). YCl3 and LuCl3 react with 1 equivalent of 2 or 3 followed by 1 equivalent Na[C5Me 5] to give (PhSCH2CH2C5H 4)(C5Me5)LnCl (Ln = Y (8a); Lu (8c)) and (EtSCH2CH2C5H4)(C5Me 5)YCl (9). [(EtSCH2CH2C5H 4)(C5Me5)LuCl (10) and 1,10-bipyridine form [(EtSCH2CH2C5H4)-(C 5Me5)Lu(bipy)]+ [(EtSCH2CH 2C5H4)(C5Me5)LuCl 2]- (11). Methylation of 8a, 8c, and 9 with LiMe results in the formation of (PhSCH2CH2C5H 4)(C5Me5)LnMe (Ln = Y (12a); Lu (12c)) and (EtSCH2CH2C5H4)(C5Me 5)YMe (13). LaCl3 and PrCl3 react with 3 equivalents of 3 affording (EtSCH2CH2C5H 4)3Ln (Ln = La (14d) and Pr (14e)), while the reaction of YbI2 with 2 equivalents of 3 gives [(EtSCH2CH 2C5H4)Yb(SCH2CH2C 5H4)]2 (15) along with ethane. The structures of 8c, 11, 14d, and 15 were determined by single-crystal X-ray diffraction.
