UNUSUAL SPONTANEOUS → ISOMERIZATION OF
UNSYMMETRICAL BENZOINS
Andrey Alexandrovich Anishchenko, Vasiliy Georgievich Shtamburg, Victor Vasilievich Shtamburg, Alexander Vladimirovich Mazepa. Abstract | | | | α-Mixed aryl(furyl)benzoins undergo spontaneous thermal isomerization to β-isomers in the absence of a base. It is facilitated by two
structural features viz. the presence of a para-halogen substituent in the aryl moiety and of a Me2NN=CH-substituent at 5-position of the
furan ring.
Key words: benzoins, arylglyoxals, isomerization
