- W1974410516 abstract "Chiral Cyclopentadienyl Complexes, Crystal Structure The reaction of [C 5 Cl 4 (SMe)]Mn(CO) 3 (la) with n-butyllithium and the electrophiles SiMe 3 Cl, CO 2 , or PPh 2 Cl regiospecifically yields the chiral 1,3-disubstituted functional cymantrene thioethers [C 5 Cl 3 (SMe)R]Mn(CO) 3 (R = SiMe 3 (2), COOLi (3a), PPh 2 (4)). 3 a can be protonated to give the corresponding carboxylic acid (3b), which in turn can be transformed to the acid chloride [C 5 Cl 3 (SMe)(COCl)]Mn(CO) 3 (3c). 3c reacts with NaN 3 to yield after work-up the urea derivative OC[[NH—C 5 Cl 3 (SMe)]Mn(CO) 3 ] 2 (3d). Using the cymantrene bisthioethers [C 5 Cl 3 (SR) 2 ]Mn(CO) 3 (R = Me, 5a, Ph, 5b) as starting materials, the carboxyl derivatives [C 5 Cl 2 (SMe) 2 (COR)]Mn(CO) 3 (R = OLi, 6a, OH, 6b, Cl, 6c) and the potential organometallic S,P-chelate ligands [C 5 Cl 2 (SR) 2 (PPh 2 )]Mn(CO) 3 (R = Me, 7a, Ph, 7b) can be obtained. The crystal structure determination of 7a (C 22 H 16 O 3 PS 2 Cl 2 Mn, monoclinic, P 2 1 /c, a = 18.714(6) A, b = 9.506(3) A, c = 14.475(3) Α, β = 109.18(2)°, V = 2432.1(12) Α 3 , Z = 4) shows an orientation of the neighbouring PPh 2 - and SMe groups, that allows chelation of an additional metal fragment." @default.
