thermal decompn.;

pyridine; 3-chloroprop-1-ene in toluene soln. of V-complex in toluene was treated with CH2=CHCH2Cl (inert atmosphere), the mixt. was stirred at room temp. for 24 h; the mother liquor contained org. compounds, products of the reaction of CH2=CHCH2Cl with either toluene or mesitylene (CLG-MS); filtered, ppt. was dissolved in pyridine, soln. was filtered and concd.to give the crystals of VCl2*4Py; identified by comparison of the IR spectrum with that of authentic sample;

in n-heptane byproducts: 1,3,5-trimethylbenzene, H2; under purified Ar atm.; soln. of V(η6-Me3C6H3)2 in heptane was treated with dry HCl; after 2 hs suspn. filtered; solid dried (vac.) at room temp.; elem. anal.;

in acetylacetone byproducts: 1,3,5-trimethylbenzene, H2; under purified Ar atm.; V(η6-Me3C6H3)2 was dissolved in neat acetyl acetone; mixt. refluxeed for 5 hs; excess of acetyl acetone removed (vac., room temp.); residue suspended in heptane; suspn. filtered; dried (vac.) at room temp.;

in n-heptane under purified Ar atm.; soln. of V(η6-Me3C6H3)2 in heptane was treated with dry HBr;

in toluene react. of V(mes)2 and MnI(CO)5 in toluene;

in ethylene glycol dimethyl ether react. of V(mes)2 and MnBr(CO)5 in DME;

in n-heptane under purified Ar atm.; soln. of V(η6-Me3C6H3)2 in heptane was treated with dry HBr;
