Synthesis of 2,5- and 2,6-bis(bromomethyl)-1,4-diphenylpiperazines and their conversion into 2,5-diphenyl-2,5-diazabicyclo[2.2.2]octane
(The American Chemical Society: The Journal of Organic Chemistry, 1971-11-05)Treatment of cis-1,5-diphenyl-3,7-dihydroxyoctahydro-1,5-diazocine (1) with phosphorus tribromide yielded a mixture of cis-2,6-bis(bromomethyl)-1,4-diphenylpiperazine (4) and cis-2,5-bis(bromomethyl)-1,4-diphenylpiperazine ... -
Comparison of through-space and through-bond interactions in four-membered ring systems
(The American Chemical Society: Journal of Physical Chemistry, 1982-09-30)Numerous authors have discussed the interactions between nondirectly bonded functions in terms of direct “though-space” orbital interactions and/or “through-bond” orbital interactions. In this study, ab initio interaction ... -
