DETAILS

Description (English)

Application
Mediates the condensation of the aldehydes with trisubstituted chloroalkenes.1 Used in the synthesis of a highly active precatalyst for ethylene oligimerization.2
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.
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.
