Sm. Ma et Lm. Venanzi, A VERSATILE RUTHENIUM CATALYST FOR THE TETRAHYDROPYRANYLATION OF ALCOHOLS AND PHENOLS, Tetrahedron letters, 34(33), 1993, pp. 5269-5272
The tetrahydropyranyl derivatives of alcohols and phenols are efficien
tly prepared in the presence of catalytic amounts of [Ru(CH3CN)3(triph

o excellent yields.
