Treatment of Warts with Topical Formic Acid

The Reduction of Nitriles to Aldehydes: Applications of Raney Nickel/Sodium Hypophosphite Monohydrate, of Raney Nickel/Formic Acid, or of Raney(Ni/Al)Alloy/Formic Acid, Respectively†

The three title reductant systems have significant advantages in generating aldehydes from nitriles. These include: the utilization of convenient hydrogen sources, namely, sodium hypophosphite monohydrate and formic acid, respectively, and of the relatively inexpensive Raney nickel and Raney (Ni/Al) alloy; the convenience of conducting the reaction(s) in aqueous media at ambient temperatures an...

Submillimeter Spectrum of Formic Acid

We have measured new submillimeter-wave data around 600 GHz and around 1.1 THz for the C isotopologue of formic acid and for the two deuterium isotopomers; in each case for both the trans and cis rotamer. For cis-DCOOH and cis-HCOOD in particular only data up to 50 GHz was previously available. For all species the quality and quantity of molecular parameters has been increased providing new mea...

Enzymic oxidation of formic acid.

Interest in the metabolic fate of formic acid has been renewed as the result of recent experiments showing active incorporation of carbon-labeled formate into normal body constituents of the pigeon (l-3) and the rat (4, 5). Prior to these findings, enzymes capable of catalyzing the oxidation of formic acid had been reported, widely distributed in plant and animal tissues (6). Only in the case o...

Reaction of atomic hydrogen with formic acid.

We study the reaction of atomic hydrogen with formic acid and characterize the radical products using IR spectroscopy in a Kr matrix and quantum chemical calculations. The reaction first leads to the formation of an intermediate radical trans-H2COOH, which converts to the more stable radical trans-cis-HC(OH)2via hydrogen atom tunneling on a timescale of hours at 4.3 K. These open-shell species ...
