Inulin and D-fructose are quantitatively converted into a mixture of Mructose dianhydrides on treatment with anhydrous hydrogen fluoride. Of the six dianhyd~des isolated, five are known compounds, whereas one, P\_Mructofuranose @-r>-fructopyranose 2,1':3,2'-dianhydride, has not been described hither

## Abstract The interaction of iodine cyanide and cyanide in aqueous solution has been reinvestigated and it has been confirmed that a complex cyanide ion, the dicyanoiodate(I) ion [I(CN)~2~]^β^ is formed. This ion has been isolated in the solid state for the first time, as its tetraphenylarsonium,
Treatment of o-glucono-l,S-or o-mannono-1,4-lactone with anhydrous hydrogen fluoride catalysed by formic or acetic acid yields 3,6-anhydro-o-glucono-and -o-mannono-1,4-lactone, respectively. Similarly, o-mannitol is converted into 1,4-anhydro-o-mannitol and subsequently into the 1,4:3,6-dianhydride,
