Baylis-Hillman Reactions of Sulfonyl Aldimines or Aryl Aldehydes with 3-Methylpenta-3,4-dien-2-one or 3-Benzylpenta-3,4-dien-2-one
《Chinese Journal of Chemistry》2007年第6期828-835,共8页施敏 郭英文 李红斌 
Project supported by State Key Project of Basic Research （Project 973） （No. G2000048007）, Shanghai Municipal Committee of Science and Technology （Nos. 04JC14083, 06XD14005）, and the National Natural Science Foundation of China （Nos. 20472096, 203900502, and 20672127）.
The attempted Baylis-Hillman reactions of sulfonyl aldimines or aryl aldehydes with 3-methylpenta-3,4-dien-2-one or 3-benzylpenta-3,4-dien-2-one gave the corresponding Baylis-Hillman adducts in moderate yields in DMSO...

XANES at Eu-L3 edge and valence of europium in SrB_4O_7: Eu and BaB_8O_(13): Eu
《Chinese Journal of Chemistry》2000年第3期294-296,共3页梁宏斌 胡天斗 王淑彬 曾庆华 裴治武 苏锵 
Project supported by the State Key Project of Basic Research (Project 973) (No. G1998061312), the National Natural Science Foundation of China (No. 29771029) and the Foundation of Laboratory of Beijing Synchrontron Radiation, Institute of High Energy Phy
The luminescent materials SrB4O7: Eu and BaB8O13: Eu were synthesized, and the valence states of europium in the materials were measured by means of XANES at Eu-L3 edge. It is found that the Eu3+ and Eu2+ ions are al...
