Abstract
 
Although listed in organic chemistry textbooks
as one of the strongest carbon acids, and in spite
of more than a hundred years of attempts to prepare
the compound, tricyanomethane (cyanoform) has
resisted isolation and characterization, either
as the carbon-acid 1 or as the dicyanoketenimine
tautomer 2. Only in the vapor phase at very low
pressure has the compound been identified from its
microwave spectrum. Here we review and partially
repeat the preparative work. With the aid of
spectroscopic and diffraction methods (including
powder diffraction) we have identified some of the
products obtained as: hydronium tricyanomethanide
(3), (Z)-3-amino-2-cyano-3-iminoacrylimide (4),
a co-crystal of 4 with sulfuric acid (or corresponding
iminium salt), and an addition product of 2 with
 hydrochloric acid (5/6). Quantum-mechanical
calculations at the MP2/6-311++g(2d,2p) level have
been made to assess the relative energies of some of
the molecules involved.

a semi-sproposito della sililazione, cercando (e non 
trovando) il triciano (trimetilsilil) metano, ho trovato il 
triciano (trimetilsililOSSI) metano
 
che si prepara da fosgene e trimetilsililcianuro

La reazione sarà presumibilmente a stadi, ma l'ordine non mi 
è noto né mi sembra autoevidente, anche se per mera 
abitudine e per dirne una a caso, direi che prima avvenga la 
sostituzione dei clori mobili e solo dopo l'addizione al 
carbonile (con un intermedio, credo noto ma non sono sicuro, 
di tipo carbonil cianuro, o chetomalondinitrile)
 
Questa reazione arriva al medesimo punto : l'interruzione 
della coniugazione dei tra ciano (seppure partendo da 
composti diversi e quindi passando per una strada in cui 
tale coniugazione non si realizza mai), mediante un legame 
di quelli difficili da rompere in modo "umpolung", il legame 
C-O, che quindi blinda il carbonio centrale in forma 
tetraedrica proprio come faceva il cloro che avevo già 
citato (o un quarto gruppo ciano).
