Solubility: sol most polar organic solvents; very sol methylene chloride; insol diethyl ether and alkanes. Form Supplied in: yellow crystals generally prepared by user from Mo(CO)6. Analysis Reagent Purity: carbonyl stretching bands at 2017 1962 cm−1 (CH2Cl2) are characteristic. Preparative Methods: straightforwardly in 97% yield hydride abstraction CpMo(CO)2(cyclohexenyl),2 which turn is following a procedure developed the parent allyl complex Hayter5 (>70% yield). This involves reflux Mo(CO)6 acetonitrile to produce Mo(CO)3(MeCN)3, addition 3-bromo-1-cyclohexene, subsequent treatment with lithium cyclopentadienide. Handling, Storage, Precautions: should be handled under nitrogen or argon. The can air short periods no significant decomposition. Solutions compound sensitive, but brief exposure reduced volume rotary evaporator. Use fume hood.
