Synthesis of sterically hindered ortho-substituted tetraphenylethenes. Electronic effects in the McMurry olefination reaction
Chung, Mee-Kyung,Qi, Guizhong,Stryker, Jeffrey M.
, p. 1491 - 1494 (2007/10/03)
Contrary to literature consensus, the McMurry olefination reaction can be extended to the direct synthesis of sterically encumbered tetrakis(2- substituted) tetraphenylethenes from the corresponding 2,2′-disubstituted benzophenones. The reaction exploits

The action of chlorohydroalane (AlH2Cl) on 1,1-bis(5-tert-butyl-2-methoxyphenyl)ethanol (3b) in ether led to a novel demethylation reaction which afforded 1,1-bis(5-tert-butyl-2-hydroxyphenyl)ethanol (5b).Hydroalane in ether is an effective reagent for se

Tetra-tert-butyltetrahydroxy- and tetrahydroxymetacyclophanes, 1 and 2 (a, n=1; b, n=2; and c, n=3), were prepared from p-tert-butylanisole by using the tert-butyl group as a posotional protective function.Acylation of 1b and 2b with Ac2O gave te
