Ito, Yoshihiko,Imai, Hiroshi,Segoe, Kazuo,Saegusa, Takeo
, p. 937 - 940 (2007/10/02)
Cyanation of acetals was achieved by t-butyl isocyanide in the presence of TiCl4, producig cyanohydrin ethers in good yields. β-(Trimethylsilyl)ethyl isocyanide in the combination with TiCl4 effected the cyanation as well.
