Adding a certain compound to certain chemical reactions, such as: 4090-55-5, name is 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4090-55-5, Formula: C5H10ClO3P
Synthesis Example 3 (Synthesis of Phosphorus Compound 3); A mixture was obtained in the same manner as in Synthesis example 1 except that 114.4 g of toluene were used in place of 114.4 g of chlorobenzene, 161.5 g of 4-phenylphenol (para-phenylphenol) (0.95 mole) were used in place of 161.5 g of 2-phenylphenol (ortho-phenylphenol) (0.95 mole) and 127.5 g of toluene were used in place of 145.6 g of chlorobenzene to add to the reaction mixture.(After-treatment) The obtained mixture was cooled to room temperature and neutralized by adding a hydrochloric acid solution which corresponds to an excess amount of triethylamine, and allowed to stand to separate an oil phase. Next, the obtained oil phase was washed with approximately 85 C water and then any liquid was removed by a centrifugal filter. The obtained solid was dried by a vacuum desiccator at 100 C, to give 253.7 g of a white solid. The purity of the obtained solid was found to be 98.7 area % by GPC. Also, if all of the solids were assumed to be an object compound, the crude yield was 84.0 %. A structure of the obtained solid was determined according to results of quantitative analysis of phosphorus by elemental analysis and absorption spectrometry using an UV spectrometer, 1H-NMR, 13C-NMR and FT-IR, and the solid was identified as 5, 5-dimethyl-2-(4′-phenylphenoxy)-1, 3, 2-dioxaphosphorinane-2-oxide (phosphorus compound 3) of the below-mentioned constructional formula. Also, a melting point of the solid was measured in the same manner as in Synthesis example 1. Quantitative analysis of phosphorus by elemental analysis and absorption spectrometry (theoretical values in parentheses): Carbon: 64.3 % (64.2 %) Hydrogen: 6.1 % (6.0 %) Phosphorus: 9.7 % (9.7 %) Melting point: 165 to 167 CIR (KBr): 3008, 1606, 1523, 1488, 1405, 1376, 1296, 1226, 1194, 1174, 1114, 1059, 1002, 934, 861, 810, 765, 720, 691, 624 cm-1 3008, 1606, 1523, 1488, 1405, 1376, 1296, 1226, 1194, 1174, 1114, 1059, 1002, 934, 861, 810, 765, 720, 691, 624 cm-1 NMR: 1H-NMR (CDC13; 300MHz); delta 7.57-7.31 (9H, m, o-PP), 4.27 (2H, d, JHH=11Hz, POCH2C (CH3)2-), 4.01 (2H, dd, JHH=11Hz, JPH=22Hz, POCH2C (CH3)2-), 1.34 (3H, s, POCH2C (CH3)2-), 0.92 (3H, s, POCH2C (CH3)2-) ppm1H-NMR (CDC13; 300MHz); delta 7.57-7.31 (9H, m, o-PP), 4.27 (2H, d, JHH=11Hz, POCH2C (CH3)2-), 4.01 (2H, dd, JHH=11Hz, JPH=22Hz, POCH2C (CH3)2-), 1.34 (3H, s, POCH2C (CH3)2-), 0.92 (3H, s, POCH2C (CH3)2-) ppm13C-NMR (CDC13; 75MHz); delta 149.7 (d, 2JPC=6Hz), 140.0, 138.1, 128.7, 128.4, 127.2, 126.9, 119.7 (d, 3JPC=5Hz) (o-PP), 78.3 (d, 2JPC=7Hz, POCH2C (CH3)2-), 32.1 (d, 2JPC=6Hz, POCH2C (CH3)2-), 21.6, 20.1 ppm
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide, other downstream synthetic routes, hurry up and to see.
