AROMATICS

Reactions

Silane Reduction of Aromatics is as follows:
Furans are reduced to tetrahydrofurans with triethylsilane under suitable catalysis. Thiophenes can be  similarly reduced.
Anthracene was reduced to 9,10-dihydroanthracene in good yield with triethylsilane and boron triflfl uoride hydrate. The partial reduction of other polyaromatics was reported.
The pyridine ring of quinoline was reduced in preference to the benzene ring. The isolated product was the  N-silylated derivative. Some of the dihydroreduction product was also observed.
