carbon monoxide in 1,2,5-trimethyl-benzene Kinetics; byproducts: Mo2I4(CO)8; satn. of the Mo(0) complex in mesitylene with CO (atm. pressure) in a gasvolumetric burette at 24.5°C, introducing of I2 as catalyst in a sealed, thin-walled flask under CO, crushing the sealed flask with a magnetically stirred bar;

in benzene React. of 3 equiv of org. compd. with stirred suspn. of Mo-complex in benzene (25°C, inert-atmosphere).; Removal of benzene, unreacted phosphine and mes after 48 h in vac., dissolving of resulting materials in benzene and passing of soln. through alumina column. Removal of benzene (vac.) gives pure complex as viscous oil.; elem. anal.;
