, p. 8451 - 8458 (2007/10/02)
Reaction of tetrazolopyridinium salts 1 with nucleophiles proceeds through the neutral intermediate 2.Ring opening of this leads to hetarylbutadienes (3, 4, 5) of different geometries.Experimental support has been provided for the theoretical supposition
THE STEREOCHEMISTRY AND MECHANISM OF THE RING OPENING REACTION OF 3-ARYLTETRAZOLOPYRIDINIUM SALTS AND THEIR V-TRIAZOLO ANALOGUES
Gelleri, A.,Messmer, A.,Nagy, S.,Radics, L.
, p. 663 - 666 (2007/10/02)
Contrary to earlier reports, the title reaction was found to yield both lE and lZ configured dienic products predicted for a disrotatory process.A novel degradation giving, via the loss of one carbon unit, tetrazolyl- and triazolyl-acrolein wasw also observed.
