Hydrides hydroxides

A number of basic materials such as hydroxides, hydrides and amides of alkaline and alkaline earth metals and metal oxides such as zinc oxide and antimony oxide are useful catalysts for the reaction. Acid ester-exchange catalysts such as boric acid, p-toluene sulphonic acid and zinc chloride are less... 

The hydroxide hydride [(Me3Si)2CH]2Sn(OH)H, on the other hand, is hydrogen bonded by O-H. .. O bridges into a dimer, with rSnH 173(2) pm.68... 

The predominant property of these salts is the ease with which nucleophiles add to the quinolinium-2-and the isoquinolinium-1-positions. Such additions are favoured in these bicyclic compounds since the products retain a complete aromatic benzene ring. Hydroxide, hydride and organometaUic nucleophiles aU add with facility, though the resulting dihydroaromatic products require careful handling if they are not to disproportionate or be oxidised. " This approach can give 2-nifluoromethyl-quinolines CFj carbanion (from trifluoro(trimethylsilyl)methane and fluoride) is added to an A -(para-methoxybenzyl)-quinolinium salt, then the A -substituent is removed and oxidation to the aromatic level achieved with ceric ammonium nitrate. ...
