Descripción

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.

Mediates the condensation of the aldehydes with trisubstituted chloroalkenes. Used in the synthesis of a highly active precatalyst for ethylene oligimerization.

Used to make bis(indenyl)chromium dimer and related products.

Used with iodoform and tetraethyl ethylenediamine to convert terminal olefins into trans-iodocyclopropanes in excellent yields.
