The proposed mechanism involves titanium(III)-mediated generation of an allyl radical species which intercepts a titanium(III)-coordinated carbonyl. Another application involves the single electron reduction of enones to generate allylic radicals which can undergo intermolecular trapping with acrylonitriles to afford Michael type adducts. [32]

The first metallocene characterised, ferrocene, was prepared the way many other metallocenes are prepared by combining alkali metal derivatives of the form MC 5 H 5 with dihalides of the transition metals: [12] As typical example, nickelocene forms upon treating nickel(II) chloride with sodium cyclopentadienide in THF.
Soros is also known for his application of the principle of reflexivity to financial markets. The idea here is that markets can create their own successes or failures merely through the belief of ...
It is kinetically labile, being readily hydrolysed by water or hydrochloric acid, and readily forms adducts with two- or four-electron Lewis bases. [ 2 ] Manganocene polymerizes ethylene to high molecular weight linear polyethylene in the presence of methylaluminoxane or diethylaluminium chloride as cocatalysts.
