Scholl reaction experimental

More procedures with experimental details for the preparation of benzanthrone can be found in the literature. " Other references related to the Bally-Scholl reaction are cited the literature. ... 

Interestingly, the oldest experimentally known isomer is formoxime (2), nowadays better known as formaldoxime (the oxime of formaldehyde—formaldehyde oxime), which was first synthesized as early as 1891. Scholl already reported that 2 is unstable with respect to slow polymerization, while Dunstan and Bossi were able to stabilize 2 as its hydrochloride salt and described its properties in 1898 . Dunstan and Bossi also reported the reaction of 2 HC1 with alkali metals yielding the sodium salt of 2, Na+ [H2C=NO] , which explodes when heated . Probably, this explosive statement was one of the first descriptions of a nitrosomethanide.
