Methylformate

The C-O-C stretching vibration in carboxylic esters is characterized by an absorption band between 1100 cm-1 and 1280 cm-1 [70]. In the case of pure methyl formate one observes a broad band of strong intensity between 1150 and 1220 cm-1. Considering the shift in aqueous solution the band at 1230 cm-1 in Fig. 2.12 could be attributed to the C-O-C stretching vibration of methylformate. 

Another advantage of the on-line MS method is the possibility to observe separately the catalyst effects on parallel reactions. This is illustrated in Fig. 4.1 for methanol electroxidation on Pt with 60% of tin. Current and mass signals for C02 and for HCOOCH3 (methylformate) during the oxidation of 1 M CH3OH on a porous platinum electrode were recorded. 

The oxidation of CH20 in the presence of 1 affords formic acid in nearly quantitative yields (eq 1). Only traces (0.5%) of CO and C02 were detected by GC in the reactions performed at 20-40 °C. No methylformate was found. 

Warshel, Levitt, and Lifson derived a partially optimised consistent force field for amides and lactams (25). It is composed of an alkane part and an amide-part. The former was taken over from analogous earlier calculations for saturated hydrocarbons (17). The potential constants of the amide-part were optimised with the help of a large number of experimental frequencies (taken from TV-methylform amide, acetamide, iV-methylacetamide, and several deuterated species) as well as experimental geometry data for 7V-methylacet-amide. The resulting force field was used for the calculation of vibrational and conformational properties of 2-pyrrolidone, 2-piperidone and e-caprolactam. 

Formamides have applications as solvents (particularly dimethylformamide (DMF) and formamide itself), as intermediates for insecticides and pharmaceuticals, and (for formanilide, PhNHC(O)H) as an antioxidant [95]. Formamides are prepared either from CO or from methylformate or formamide, which are themselves prepared from CO. 

Halothiophenes take part in Pd-catalyzed alkoxycarbonylations in the presence of CO, alcohol and base. In order to avoid the inconvenience of pressurized carbon monoxide, alkyl formate may be used as a safe surrogate [130], In one of the many examples, 2-Iodothiophene was carbonylated to the corresponding methyl ester using methylformate in place of CO. 

There is no doubt that this reaction is made up of several series and/or parallel reactions. Mass spectroscopic measurement showed that formaldehyde and formic add are produced during the oxidation of methanol on platinum in add solution. Using gas chromatography, methylformate...

The reaction with disubstituted formamides and phosphorus oxychloride, called the Vilsmeier or the Vilsmeier-Haack reaction, is the most common method for the formylation of aromatic rings.285 However, it is applicable only to active substrates, such as amines and phenols. Aromatic hydrocarbons and heterocycles can also be formylated, but only if they are much more active than benzene (e.g., azulenes, ferrocenes). Though N-phenyl-N-methylform-...
