21. Unexpected organic chemistry tabelarized and unfinished (Tetrahedron Letters 1995)

  I have unpublished results. I mean, I attempted to publish a work entitled Unusual organic chemistry in tetrahedron Letters 2014. This work was rejected by the editor in 2015. This fact completely stopped my other works with similar subject. I will not to try publish works about the words unexpectedunprecedented and even abnormal which we can find in many chemical publication issued in famous chemical journals. Maybe it is too early time to this a little more humanistic approach to chemistry. Okay, it is not my first and not my last defeat. Anyway, I want to show a small piece of my approach to find a chemical context of the word unexpected in  Tetrahedron Letters 1995. The table below shows my first attempts to find some order within this problem.
