Reference of 623-12-1,Some common heterocyclic compound, 623-12-1, name is 1-Chloro-4-methoxybenzene, molecular formula is C7H7ClO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
The appropriate quantity of stock solution C was added to a 4 mL vial containing the aryl chloride (1.00 mmol) and potasium terf-butoxide (123 mg, 1.10 mmol) in 1.5 mL of toluene. The aromatic thiol (1.00 mmol) was then added, and the vial sealed with a cap containing a PTFE septum. The mixture was heated at 110 0C until the chloroarene was consumed, as determined by GC. Silica gel (0.5 g) was then added, and solvents were evaporated under reduced pressure. The crude residue was purified by column chromatography on silica gel using hexane or a mixture of hexane and ethyl acetate as eluent. Aryl sulfides were isolated in the yields reported in Table 4.4-Methoxyphenyl phenyl sulfide (Table 4, entry 1).[49] 100 muL of stock solution C were used. A 50:1 mixture of hexane/ethyl acetate was used as chromatography eluent. 98% yield. Colorless liquid. 1H NMR (CDCl3): delta = 7.23 (d, J= 8.8 Hz5 2H), 7.06-7.02 (m, 2H), 7.00-6.93 (m, 3H), 6.71 (d, J= 8.8 Hz5 2H)5 3.62 (s, 3H). 13C NMR (CDCl3): delta = 159.7, 138.5, 135.3 (2C), 128.8 (2C), 128.1 (2C), 125.7, 124.2, 114.9 (2C)5 55.3.
The synthetic route of 623-12-1 has been constantly updated, and we look forward to future research findings.
