  Reaction of 7 with acetic anhydride (CAS 108-24-7)

• Image Source:

  Stereoselective synthesis and properties of 1,3-bis(dicyanomethylidene)indane-5-carboxylic acid acceptor fragment containing nonlinear optical chromophores

• Mark:

  Scheme 2

• Associated context:

  The compound initially was poorly soluble, but extended heating in Ac₂O led to the dissolution of the material. As the acquired crystal structure revealed, the acylation of  7 had happened, yielding the reaction product 7b (Scheme 2).
