    Synthesis, Spectral and Microbial Studies of Some Novel Schiff Base Derivatives of 4-Methylpyridin-2-amine by J. J. Vora, S. B. Vasava, K. C. Parmar, S. K. Chauhan, S. S. Sharma

    Published 2009-01-01
    “…Schiff base derivatives of N-{(1E)-[3-(mono or di-substituted aryl)-1-phenyl-1H-pyrazol-4-yl]methylene{-4-methylpyridin-2-amine were synthesized by the acid catalyzed condensation of 3-(mono- or di- substituted aryl)-1-phenyl-1H-pyrazole-4-carbaldehyde derivatives with 4-methylpyridin-2-amine. …”

    Diversity-oriented synthesis of stereodefined tetrasubstituted alkenes via a modular alkyne gem-addition strategy by Xuan Di, Sitian Zhou, Yali Qin, Wenjun Li, Yue Zhang, Jie Zhang, Xu Shen, Jie Han, Jin Xie, Hongming Jin

    Published 2025-01-01
    “…The merit of this approach is demonstrated by programmed assembly of diverse functionalized multi-arylated alkenes, especially enabling the stereospecific synthesis of all six possible stereoisomers of tetraarylethene (TAE) derived from the random permutation of four distinct aryl substituents around the double bond. …”

    Evolution Characteristics of a High-Level Asymmetric Fracture-Seepage Community and Precise Coalbed Methane Drainage Technology during Mining of Outburst-Prone Coal Seam Groups by Hongbing Wang, Zhiheng Cheng, Tie Li, Liang Chen, Quanle Zou, Shengli Yang, Jialin Cao

    Published 2021-01-01
    “…The aim of this study is to explore the coupling relationship between fractures in overlying strata and gas seepage fields for pressure relief during mining of outburst-prone coal seam groups and to quantitatively characterize the distribution characteristics of favorable areas for coalbed methane (CBM) drainage in mining-induced fractures of overlying strata. …”
