Abstract
Photolysis of (Me2SiSiMe2)[(eta(5)-t-BuC5H3)Fe(CO)](2)(mu-CO)(2) (2c) in the presence of P(OPh)(3) ligands afforded only H3Me2SiSiMe2C5H3-t- Bu)Fe-2(CO)P(OPh)(3)(mu-CO)(2)] (3c), whereas similar treatment of 2t yielded only the trans isomer 3t. When 3c and 3t were heated, in xylen e, the cis compound (3c) rearranged to the trans product [{Me2Si(eta(5 )-t-BuC5H3)Fe}(2)(CO)(3)P(OPh)(3)] (4t), while the trans compound (3t) afforded the cis product [{Me2Si(eta(5)-t-BuC5H3)Fe}(2)(CO)(3)P(OPh)( 3)] (4c); thus, the rearrangement is stereospecific.
