The best cocatalysts are those derived from organoaluminum or organo-aluminum chlorides. Certain organometallic complexes, e.g., RMgBr... 

A/ "-Hexamethylguanidiniuin chloride (542 Scheme 100) is readily reduced by means of NaH in the presence of sodium alkoxyaluminates, boronic acid esters or aluminum alkoxides J Organo-metallic derivatives such as phenyllithium, 2-thienyllithium or 2-furanyllithium or sodium acetylides add to the guanidinium salt to give the corresponding orthoamides. From tetrakis(dimethylamino)methane and phenylacetylene l-phenyltris(dimethylamino)-l-propyne (543 equation 242) was prepared. ... 

Various Ziegler-Natta and ROMP caalysts based on group IV-VIII transition metal salts showed to be very active and selective in the polymerization of both exo-and ew(7o-dicyclopentadiene [151-155]. Thus, binary Ziegler-Natta systems derived from chromium, molybdenum, and tungsten halides associated with organo-aluminum compounds form addition and ring-opened polymers [Eq. (94)]. 

While the salts of lithium such as carbonate, sulfate, nitrate and chloride do not require special equipment for handling, all products derived from metallic lithium (e.g., organo-lithium compounds, lithium aluminum hydride) have a high reactivity and may even ignite when exposed to (humid) air. Therefore, production and handling must be carried out under an inert gas (e.g.. 

Organo-polygermanium hydrides are prepared by exchange of halogen with lithium aluminum hydride (l), by hydrolysis of organogermanium metal derivatives (II) and by partial hydrogermylation of olefins (III).
