Abstract A novel apparatus for the complexation of arenes with Cr (CO) 6 is described. This, and the modification of the reaction procedure shortens the reaction time, and improves the yields of η 6-arenetricarbonylchromium complexes. The method was tested for representative samples of arenes. The same method was used for complexation of arenes with Mo (CO) 6 and W (CO) 6. In all cases, except for (η 6-C 6 H 5 X) Cr (CO) 3 (X= F, Cl) ...
