| Abstract: | The betain‐like SOC2(PPh3)2 ( 1a ) reacts with Mn2(CO)10] in THF to produce the salt‐like complex (CO)4Mn(SOC2{PPh3}2)2]Mn(CO)5] ( 2 ). 1a is bonded via the sulfur atoms which are arranged in trans position in the octahedral environment of the manganese atom. With InCl3 from CH2Cl2 solution the addition product Cl3In(SOC2{PPh3}2)] ( 3 ) is obtained along with the salt (H2C{PPh3}2)InCl4]2 ( 4 ), which is the result of proton abstraction from the solvent. The crystal structures of 2· 0.5THF and 4· CH2Cl2 are reported. The compounds are further characterized by IR and 31P NMR spectroscopy. |
