thionyl chloride in tetrahydrofuran THF soln. of SOCl2 was slowly added to a stirred soln. of Mo-complex inTHF at room temp. under N2 atmosphere; solvent was removed under vac., residue extd. with Et2O, sepd. by a column chromy. (eluent petroleum ether followed by Et2O-petroleum ether);

tetrahydrofuran; thionyl chloride in tetrahydrofuran THF soln. of SOCl2 was added dropwise (15 min) to a stirred soln. of CpMo(CO)3Na in THF at -97°C under nitrogen atmosphere; evapd., residue was extd. with Et2O, chromd. on a SiO2 column (eluent Et2O-light petroleum, then Et2O); (CpMo(CO)3)2 was identified by IR and (1)H NMR spectra, elem. anal. for CpMoCl(CO)3 and THF-substituted dimer (crystd. from Et2O-petroleum ether);

thionyl chloride in tetrahydrofuran THF soln. of SOCl2 was added dropwise to a stirred soln. of CpMo(CO)3Nain THF at room temp. under nitrogen atmosphere;
