Single-Step Insertion of Organic Sulfur Into a Fe₆C Carbide Carbonyl Cluster, Including the Natural Amino Acid L-Cysteine: Vibrational Circular Dichroism and Chirality Transfer.

ABSTRACT: We present a straightforward and versatile synthetic route to Fe₆C carbide carbonyl clusters containing organosulfur ligands, including the chiral amino acid L- and D-cysteine. Reaction of the reduced cluster [NEt₄]₄[Fe₆C(CO)₁₅] (1) with thiols (RSH) or disulfides (RSSR) affords novel functionalized hexa-iron carbide clusters [NEt₄]₃[Fe₆C(CO)₁₄(SR)] (R = CH₃, 2; C₆H₅, 3; p-C₆H₄CH₃, 4; L-cysteine, L-5; D-cysteine, D-5). Compounds 2-5 have been characterized by Fourier transform infrared (FT-IR), ¹H and ¹³C{¹H} nuclear magnetic resonance (NMR) spectroscopy, and the molecular structures of 2-4 have
