| | Tricarbonyl(naphthalene)chromium Usage And Synthesis |
| Uses | Tricarbonyl(naphthalene)chromium is used as a catalyst for the hydrogenation of alkynes, 1,3-dienes, dienol acetates, and for the isomerization of conjugated dienes,
silyloxymethyl- and aminomethylbutadiene. | | Preparation | Tricarbonyl(naphthalene)chromium is prepared in 75-83% yield by treating naphthalene with Hexacarbonylchromium in dry decalin.[1] | | storage |
Tricarbonyl(naphthalene)chromium should be handled under a nitrogen or argon atmosphere, and a glove box would be
ideal. The solid should be stored at low temperature, in the dark, under nitrogen.
| | Purification Methods | Purification of Tricarbonyl(naphthalene)chromium: recrystallized under nitrogen from petroleum ether. | | References | 1. Fischer, E. O.; Ofele, K.; Essler, H.; Frohlich, W.; Mortensen, J. P.; Semmlinger, W. CB 1958, 91, 2763 |
