| Application: | Mediates the condensation of the aldehydes with trisubstituted chloroalkenes. Used in the synthesis of a highly active precatalyst for ethylene oligimerization. |
| Application: | The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties. |
| Application: | Used to make bis(indenyl)chromium dimer and related products. |
| Application: | Used with iodoform and tetraethyl ethylenediamine to convert terminal olefins into trans-iodocyclopropanes in excellent yields. |
