experimental part, p. 2227 - 2237 (2010/04/25)
Silica-supported zinc chloride (SiO2-ZnCl2) and novel alumina-supported sodium hydrogensulfate (NaHSO4-Al 2O3) as recyclable heterogeneous catalysts have been used for the mild trimethylsilylation of hydroxyl groups under ambient conditions. This procedure also allows for the selective protection of primary and secondary alcohols in the presence of tertiary alcohols.

scheme or table, p. 2584 - 2595 (2009/08/15)
Alumina sulfuric acid as a recyclable catalyst conducts the transformation of various types of alcohol, phenols, and oximes with hexamethyldisilazane (HMDS) to the corresponding O-trimethylsilylated compounds in good to excellent yields under mild and ambient conditions with short reaction times. The method is highly selective for the conversion of primary alcohols in the presence of secondary and tertiary alcohols. Additionally, the catalyst can be easily recovered and reused at least eight times without detectable loss of reactivity.

One-pot synthesis of α-substituted hydroxylamine derivatives from aldehydes using lithium perchlorate/diethyl ether as a catalyst
Heydari, Akbar,Mehrdad, Morteza,Tavakol, Hossein
, p. 1962 - 1964 (2007/10/03)
O-(Trimethylsilyl)oxime ethers, generated in situ by reaction of aldehydes and O-(trimethylsilyl)hydroxylamine in lithium perchlorate/diethyl ether solution, are highly reactive species and undergo facile reaction with silylated nucleophiles, such as trimethylsilyl cyanide and the binary reagent (MeO)3P/Me3SiCl, to give α-substituted hydroxylamine derivatives.
