β-oxopropyl formate as a formylating agent of sterols
Kabouche, Ahmed,Kabouche, Zahia
, p. 2127 - 2128 (1999)
Propargylic alcohol reacts with formic acid in the presence of mononuclear catalysts of ruthenium to selectively afford β-oxopropyl formate which has been shown as an excellent mild formylating agent of sterols when the reaction is catalyzed by 1,5-diazabicyclo[4.3.0]non-5-ene (DBN).

Trimethylsilylation of alcohols was achieved using 1,1,1,3,3,3- hexamethyldisilazane (HMDS) as silylating agent, in the presence of polyvinylpolypyrrolidoniume tribromide in acetonitrile at room temperature. Also a variety of alcohols were converted into alkyl formates by ethyl formate and a catalytic amount of polyvinylpolypyrrolidoniume tribromide under solvent free conditions at room temperature.

experimental part, p. 39 - 43 (2010/09/03)
A simple, rapid and efficient microwave-assisted procedure for the formylation of aniline derivatives and alcohols, using a heterogeneous (HCOOH/SiO2) system under solvent-free conditions is reported. The method is applied to a set of amines, alcohols and thiols and short reaction times (10 min) with high yields are reported. This protocol introduces a practical and viable green technology of solvent-free and catalyst-free reactions.
