Study of Effects on the Coordination of Thioether Ligands, 2. Stereospecific Ligand Substitutions in Manganese (I) Complexes

Treatment of fac- and fac- with silver hexafluorophosphate yields the η3-tripodal manganese complexes PF6 (7) and PF6 (9), respectively, whereas the reaction of CH3C(CH2PPh2)2(CH2SH) with Mn(CO)5Br gives directly Mn(CO)3 (11).Both ionic complexes 7 and 9 undergo stereospecifically ligand substitution upon treatment with Br(-), I(-), N3(-), SCN(-) and CN(-) to give syn-fac- and syn-fac- (X = Br, I, SCN, N3, CN) respectively, but the neutral complex 11 fails to undergo such a substitution reaction with these ions.However, reaction of I(-) with the complex Mn(CO)3>BF4 (20) , which is obtained from the S-alkylation of 11 with the (CH3)3OBF4, affords syn-fac-Mn(CO)3I (22s) exclusively.The possible reaction mechanism of this ligand substitution is discusssed. - Key Words: Tripodal ligands/ Phosphane ligands/ Thioethers/ Manganese complexes
