Oe. Nasakin et al., 2 ALTERNATIVE PATHWAYS FOR THE INTERACTION OF HEXACYANOCYCLOPROPANE WITH NUCLEOPHILES, Mendeleev communications, (5), 1994, pp. 185-186
Methanol molecules add to the cyano groups of hexacyanocyclopropane 1
in the presence of sodium methylate to give 1,4-adduct 2. The interact
ion of 1 with N-methylpyridinium iodide leads to opening of the cyclop
ropane ring and to the formation of propenide 3 and iodine cyanide 4;
the structure of 2 was established by an X-ray crystallographic study.
