New Advances in Chemical Research in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, preparation and modification of special coatings. COA of Formula: C8H5ClS. Introducing a new discovery about 66490-33-3, Name is 4-Chlorobenzo[b]thiophene
The present invention provides a method for preparing according to […], comprising the following steps: in order to 7 – (4-chloroprene yloxy) – 1H-quinolin-2-one (6) as the starting material, and piperazine single hydrochloride mono-substituted reaction occurred, generating intermediate 7 – (4-piperazine-butoxy) – 1H-quinolin-2-one hydrochloride (13), 13 with 4-chlorobenzo [b] thiophene (14) prepared by the catalytic coupling reaction […] final product (1). The method for preparing […] of the invention, the raw material is easy to obtain, simple process, the operation is convenient, high total yield (the overall yield is up to 75%) and easy for industrial production. The reaction formula is as follows: . (by machine translation)
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 66490-33-3 is helpful to your research.
