Chlorobis(ethylene)rhodium (I) dimer → HCID 131716647, compound

Participants

Reaction Steps

All operations are performed under an inert atmosphere and with dry, degassed solvents. Lithium pentamethylcyclopentaindenide powder (720 mg, 5.06 mmoles) is added in several portions to a cooled slurry of 1.0 g (2.54 mmoles) of chlorobis(ethylene)rhodium(I) dimer in 40 ml of THF. The mixture darkens as it comes to room temperature. The mixture is stirred several hours at room temperature then the solvent is stripped off at reduced pressure. The black residue is taken up in hexane, filtered and passed through a 6-inch column of activated neutral alumina with hexane eluent. The yellow fraction is collected which yields 980 mg of pentamethylcyclopentadiene rhodium bisethylene as a yellow solid (64 percent yield).
