Abstract:
CpMoMn(CO)5(mu-S2), 1 reacts with 1,4-benzoquinone to yield CpMoMn(CO)5(mu-S2C6H2O2), 2 containing a 1,4-quinonedithiolato ligand formed by replacing two of the hydrogen atoms on one of the C-C double bonds of 1,4-benzoquinone with sulfur atoms from the disulfido ligand in 1. Compound 2 was reduced with hydrogen to yield CpMoMn(CO)5[mu-S2C6H2(OH)2], 3 which contains a 1,4-hydroquinonedithiolato ligand. Compound 3 was reoxidized to 2 with ferrocenium hexafluorophosphate.
