51% | General procedure: To a mixture of compound 3(1.5 mmol) and 3M HCl (1.53 mL) at 0 °C, a solution of sodium nitrite (NaNO2, 1.58mmol) in water (3 mL) was added dropwise while maintaining the temperaturebelow 5 °C. After stirring for 30 min, asolution of diazonium chloride was prepared. Subsequently, a solution ofdiazonium chloride was added gradually to a mixture of phenols/anilines (4a,b; 6a?f;8a?k or 9a?e, 1.5 mmol), and ethanol (3 mL) at 0-5 °C. The reaction mixture was adjusted to pH 8-9 with 1 Maq. NaOH. After addition, the mixture was continued to stir for 3-6 h. Thesolid was collected, washed with water (3×15 mL), dried and purified by PTLC orsilica gel column chromatography to give the target products IIa?x. |

With molybdenum(VI) oxide; In ethanol; at 280℃; for 4h;Inert atmosphere; | General procedure: 2.0 g of guaiac acid (purchased in Tianjin Guangfu Technology Co., Ltd.), 0.5 g of MOS catalyst and 100 ml of ethanol were placed in a 300 ml reaction vessel, and the air in the reaction vessel was replaced with nitrogen. The temperature was raised to 280 C, and the reaction was stirred for 4 h. After the reaction was completed, the mixture was filtered under suction and rotary evaporated. The liquid product was subjected to qualitative analysis on a gas chromatography-mass spectrometer (GC6890-MS5973, Agilent), and the internal standard was added. Quantitative analysis by gas chromatography. The chromatogram was performed on an HP-5ms, 30m X 0.25mm X 0.25mum capillary column. The conversion of the raw guaiacol is calculated by (initial guaiacol moles - residual guaiacol moles) / (initial guaiacol moles) X100%, and the selectivity of the product hydrocarbyl phenol is (hydrocarbyl phenol) The number of moles / (molar guaiacol moles) X 100 % was calculated. Among the guaiacol conversion products, ethyl phenols include o-ethyl phenol, 2,5-diethyl phenol, 3,5-diethyl phenol, and propyl phenols include 2,6-diisopropyl phenol. , 2,4-diisopropylphenol, 2,4,6-triisopropylphenol, butyl phenols including 2,5-di-sec-butylphenol, 2,6-di-tert-butylphenol, 2, 4-di-tert-butylphenol, 2,6-di-tert-butyl-p-ethylphenol, pentanols include 2,4-di-tert-amylphenol, others include o-ethoxyphenol, o-ethoxybenzene Methyl ether, p-ethyl guaiacol, 2,6-diisopropylanisole). |
