摘要
本文报导了两种新型罗丹宁苯并噻唑偶氮试剂5—（2—苯并噻唑偶氮）—罗丹宁[BT．ARH]和5—[2—（6—溴苯并噻唑偶氮）]—罗丹宁[Br—BTARH]的合成方法，并通过UV光谱、IR光谱和元素分析确定了试剂的分子式和结构，测定了熔点和电离平衡常数，讨论了试剂在不同酸碱条件下的可能存在形式，重点研究了试剂与金属钯（Ⅰ）的配位反应．
The syntheses of two new kinds of benzothiazole azo rhodamine reagents: 5 (2-benzothiazole azo)-rhodamine [BTARH] and 5-[2-(6-bromine benzothiazole azo)]-vhodamine:[Br-BTARH] are reported in this paper. The molecular formulas and strctures are identified by UV spectrum. IR spectrum and wltimate analysis. Their melting points and pKa are determined and their probable constitutions existed as defferent conditions of acid or basic are discussed. The coordination reactions of Pd (Ⅱ) with reagents is focal point of vesearch.
