The reaction of dicymantrenyl ketone with the Grignard reagent 2,4,6-Me3C6H2MgBr in THF occurs as the insertion of the mesityl substituent in the -position of one of the cyclopentadienyl rings to give (2-mesitylcymantrenyl) cymantrenyl ketone (4), rather than as addition at the C=O...
The reaction between Re(CO)5Cl and di-2-pyridylketone benzoylhydrazone (dpkbh) in refluxing toluene gave fac-Re(CO)3(dpkbh)Cl in good yield. Spectroscopic and electrochemical measurements on fac-Re(CO)3(dpkbh)Cl revealed strong solvent–solute interaction, as manifested by the sensitivity of...
