Boron Trifluoride as a Cyclodehydrating Agent: Synthesis of Aryl Thiocyanates via Pyrylium Tetrafluoroborates

5,6-Dihydro-2,4-diphenylnaphthopyrylium thiocyanate (5) has been prepared in excellent yield.It reacts with primary arylamines to yield the corresponding pyridinium thiocyanates (6) in yields 60percent, which can undergo solvolysis in chlorobenzene

Heterocycles in Organic Synthesis. Part 36. An Alternative to the Gattermann Reaction for the Conversion of Anilines into Thiocyanates

5,6-Dihydro-2,4-diphenylnaphthopyrylium thiocyanate is prepared in high yield.It reacts with primary arylamines to yield the corresponding fused pyridinium thiocyanates which when pyrolysed with a KNCS-NaCNS eutectic at ca. 220 deg C give the aryl thiocyanates in yields averaging 80percent.
