Thermally robust metallacycles (L=<(2-CH2C6H4)2>^2-, M=Ti, Zr, Hf) and have been obtained from the newly developed reagents, L2 and L2, as has the silylated derivative, <2-(Me3SiCH2)C6H4>2.A new radical anion of 9,10-dihydrophenanthrene derived from the reaction of lithium and LCl2 or LBr2 in thf has been detected.
