In 2020,Dalton Transactions included an article by Sun, Xiaoman; Meng, Fanyu; Su, Qing; Luo, Kexin; Ju, Pengyao; Liu, Ziqian; Li, Xiaodong; Li, Guanghua; Wu, Qiaolin. Recommanded Product: 5-(tert-Butyl)-4-hydroxyisophthalaldehyde. The article was titled 《New catalytically active conjugated microporous polymer bearing ordered salen-Cu and porphyrin moieties for Henry reaction in aqueous solution》. The information in the text is summarized as follows:
A catalytically active conjugated microporous polymer (SP-CMP-Cu) was facilely constructed with condensation polymerization of salen-Cu [salen = N,N’-bis(3-tertbutyl-5-formylsalicylidene) ethylenediamine] and pyrrole. The as-synthesized SP-CMP-Cu was completely characterized by powder X-ray diffraction (PXRD), Fourier transform IR (FT-IR) spectroscopy, thermogravimetric anal. (TGA), XPS, and energy-dispersive X-ray (EDX) anal. The morphol. features of SP-CMP-Cu were revealed by SEM and transmission electron microscopy (TEM). According to N2 adsorption/desorption isotherm, Brunauer-Emmett-Teller (BET) surface area of SP-CMP-Cu was calculated to be 252 m2 g-1 with a total pore volume of 0.178 cm3 g-1. SP-CMP-Cu exhibited an outstanding catalytic performance for Henry reaction in aqueous solutions with excellent conversion and good selectivity. Moreover, SP-CMP-Cu can be reused for up to five consecutive runs without any significant loss in its catalytic efficiency.5-(tert-Butyl)-4-hydroxyisophthalaldehyde(cas: 153759-59-2Recommanded Product: 5-(tert-Butyl)-4-hydroxyisophthalaldehyde) was used in this study.
5-(tert-Butyl)-4-hydroxyisophthalaldehyde(cas: 153759-59-2) belongs to phenols.Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according to the IUPAC Gold Book).Recommanded Product: 5-(tert-Butyl)-4-hydroxyisophthalaldehyde
