Electric Literature of 1436-59-5, An article , which mentions 1436-59-5, molecular formula is C6H14N2. The compound – cis-Cyclohexane-1,2-diamine played an important role in people’s production and life.
A series of novel beta-hydroxy-beta-bis(trifluoromethyl)-imines (2a-j) and di(beta-hydroxy-beta-bis(trifluoromethyl))-diimines (3a-f) were prepared in moderate to good yields via a simple two-step approach: first, beta-hydroxy-beta-bis(trifluoromethyl)-ketones (1a-c) were obtained by a catalyst-free aldol reaction between liquid hexafluoroacetone sesquihydrate and ketones (acetone, acetophenone, and pinacolone, respectively); then, condensation of the latter fluorinated beta-ketols 1a-c with primary amines or diamines was achieved in the presence of Lewis (montmorillonite, InBr3, La(OTf)3) or Bro?nsted (PTSA) acid catalysts. The molecular structures of mono- and di-beta-hydroxy-beta-bis(trifluoromethyl)-(di)imines 2e,h and 3a,f were determined and found to exhibit strong intramolecular {double bond, long}(R)N?H-O hydrogen bonding.
