  2. Methoxy group - Wikipedia

    en.wikipedia.org/wiki/Methoxy_group

    In nature, methoxy groups are found on nucleosides that have been subjected to 2′-O-methylation, for example in variations of the 5′-cap structure known as cap-1 and cap-2. They are also common substituents in O -methylated flavonoids , whose formation is catalyzed by O-methyltransferases that act on phenols , such as catechol- O -methyl ...

  3. Trimethyl orthoformate - Wikipedia

    en.wikipedia.org/wiki/Trimethyl_orthoformate

    Trimethyl orthoformate is a useful building block for creating methoxymethylene groups and heterocyclic ring systems. It introduces a formyl group to a nucleophilic substrate, e.g. RNH 2 to form R-NH-CHO, which can undergo further reactions.

    The strongest line in the infrared spectrum is at 1330 cm −1 followed by lines at 3010 cm −1 and 1185 cm −1. Its melting point is −161.5 °C, and its boiling point is −20.2 °C. Vapour pressure is given by log P = 6.1385 + 1.75 log T − 1393.3/ T − 0.007735 T , where T is temperature in kelvins . [ 5 ]

    And finally, the centimetre and square centimetre are used in the normal way to measure thickness and area. The cm corresponds in the permeability equations to the thickness of the material whose permeability is being evaluated, the cm 3 STP cm2 s −1 to the flux of gas through the material, and the cmHg to the pressure drop across the ...

    CH 3 OC 6 H 5 + (CH 3 CO) 2 O → CH 3 OC 6 H 4 C(O)CH 3 + CH 3 CO 2 H. Unlike most acetophenones, but reflecting the influence of the methoxy group, methoxyacetophenone undergoes a second acetylation. Many related reactions have been demonstrated. For example, phosphorus pentasulfide (P 4 S 10) converts anisole to Lawesson's reagent, [(CH 3 OC ...
