Synthesis thiab Catalysis
2-Methyl-4-methylthiophenylboronic acid yog tshwj xeeb hauv kev siv cov organic synthesis thiab catalysis. Piv txwv li, Klingensmith, Bio, thiab Moniz (2007) tau qhia nws lub luag haujlwm hauv kev sib txuas ntawm 4-methyl-2-thiopheneboronic anhydride, qhia txog nws cov khoom siv hauv Suzuki-Miyaura cov tshuaj tiv thaiv, ib hom kev sib txuas ntawm cov tshuaj tiv thaiv. tsim biaryl compounds (Klingensmith, Bio, & Moniz, 2007). Górska et al. (2011) tau tshaj tawm nws daim ntawv thov hauv kev sib xyaw ua ke 5-Carboxymethyl-2-(4-methylthiophenyl)-1,3,2-dioxaborolan-4-ib qho, uas yog siv hauv enantioselective txo qis ntawm ketones (Górska li al., 2011).
Material Science thiab Nanotechnology
Hauv cov ntaub ntawv tshawb fawb, Tanaka, Fujita, thiab Nishide (2007) tau tshawb fawb txog kev siv methylthiophenylboronic acid hauv kev tsim cov yeeb yaj kiab ntawm tus kheej ntawm polythiophene nrog kub nanoparticles, ua kom pom nws lub peev xwm hauv kev siv hluav taws xob (Tanaka, Fujita, & Nishide, 2007). Al-Masri, Kricheldorf, thiab Fritsch (1999) siv derivatives ntawm methyl-substituted diaminoterphenylenes, npaj siv cov tebchaw nrog rau methylthiophenylboronic acid, rau synthesizing tshiab polyimides nrog rau tej kev siv nyob rau hauv kev sib cais roj (Al-Masri, Kricheldorf, 19).
Environmental Chemistry
Nyob rau hauv cov ntsiab lus ntawm ib puag ncig chemistry, Zuanazzi, Ghisi, thiab Oliveira (2020) tau ua ib qho kev soj ntsuam scientometric ntawm cov tshuaj lom neeg muaj feem cuam tshuam xws li 2,4-D tshuaj tua kab mob, uas yog qhov tseem ceeb rau kev nkag siab txog kev cuam tshuam ib puag ncig ntawm cov qauv tshuaj zoo sib xws ( Zuanazzi, Ghisi, & Oliveira, 2020).
