strained cyclic ether was effectively cyanated by trimethylsilyl cyanide ((CH3)3SiCN) with its ring-opening to give 5-(trimethylsiloxy)pentanenitrile in 82% yield at 120°C for 23 h in the presence of a catalytic amount of Co2(CO)8. Several tetrahydrofuran derivatives having methyl and alkoxyl groups also reacted with trimethylsilyl cyanide to give the corresponding 5-siloxy nitriles in 25–88% yields.
