LiOTf

The same authors have recently shown that in the presence of liOTf as an additive (20 mol %), the same precatalyst [RuTp(PPh3)(MeCN)2]PF6 (10 mol %) provided the selective cleavage of the carbon-carbon triple bond of terminal propargylic alcohols to form an olefin and CO (Eq. 14) [90],... [Pg.148]

This polymer assumes a smectic B-type liquid-crystalline phase when cast from solution. Then, using LiCF3S03 (LiOTf) as the alkali metal salt (Li/O = 0.4), a conductivity in excess of 1 x 10 2 Q m l is achieved at room temperature, the amorphous EO matrix effectively remaining above its Tg. The molecular architecture of the whole structure is depicted in Fig. 8.9. [Pg.265]

The aminolysis of oxiranes occurs with similar success in the presence of LiOTf (Sch. 70). As mentioned above, it is usually recommended that the reactions are conducted in MeCN. Acetone and THF, however, gave similar results in terms of reaction rate. LiOTf is poorly soluble in CH2CI2 or toluene and the aminolysis must thus be investigated at low concentrations, when the salt is completely soluble [125]. [Pg.54]
