(1960) and of the slightly modified fluorescence method of Caspersson (1970, 1971) after QM-staing. In both patients the size of the Y resembled that of the pair(More)
Ru-catalyzed synthesis of mixed alkyl–alkyl acetals via addition of primary alcohols to allyl ethers has been extended to include long-chain and/or functionalized substrates. The catalytic systems for these reactions were generated from RuCl2(PPh3)3 and [RuCl2(1,5-COD)]x and phosphines [PPh3 or P(p-chlorophenyl)3] or SbPh3. Of particular importance is the(More)
