Dimethyl group
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH3. In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in … See more Methyl cation The methylium cation (CH+3) exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the CH+3 cation, and this … See more A methyl group may rotate around the R–C axis. This is a free rotation only in the simplest cases like gaseous methyl chloride CH3Cl. In most molecules, the remainder R breaks the C∞ symmetry of the R–C axis and creates a potential V(φ) that restricts the … See more • AdoMet See more The reactivity of a methyl group depends on the adjacent substituents. Methyl groups can be quite unreactive. For example, in organic compounds, the methyl group … See more In the special case where one hydrogen is replaced by deuterium (D) and another hydrogen by tritium (T), the methyl substituent becomes chiral. Methods exist to produce optically pure methyl compounds, e.g., chiral acetic acid (CHDTCO2H). … See more French chemists Jean-Baptiste Dumas and Eugene Peligot, after determining methanol's chemical structure, introduced "methylene" from the See more WebThe trimethylsilyl protecting group has been in use for many years. It is typically introduced via two common, commercially available reagents, namely, hexamethyldisilazane and …
