Abstract The synthesis and characterisation of a small library of Co and Cu derivatives (29 examples) incorporating the (Z)-1-R1-2-(4’,4’-R2-2’-oxazolin-2’-yl)-eth-1-en-1-ate (1: R1 = alkyl or aryl; R2 = H or Me) skeleton is described. In the case where R2 = H, solid-state stable Co(II) materials of formula Co(κ2-N,O-L)2 could, in some cases, be obtained following base-induced deprotonation of 1 +
摘要包含(Z)-1-R1-2-(4',4'-R2-2'-恶唑啉-2'-基)-的Co和Cu衍生物小文库的合成和表征(29个例子)描述了eth-1-en-1-ate(1:R1 =烷基或芳基; R2 = H或Me)骨架。在R2 = H的情况下,在某些情况下,在碱诱导的1 + H脱质子化并用水合CoX2处理后,可以获得式Co(κ2-N,OL)2的固态稳定Co(II)材料盐。这些络合物显示出氧化还原诱导的溶液分解行为,从而给出了Co(κ2-N,O-1)3作为一种可分离的产物。只有在R1 = Ph和R2 = H的情况下才能获得稳定的Cu(II)配合物。在R2 = Me的情况下,扭曲的四面体Co(II)化合物(也是Co(κ2-N,O-1) 2)如上所述获得(十二个例子)。化学计量相似的Cu(II)的方形平面导数,同样被隔离(11个新示例)。与R2 = H反应相反,发现所有这些后一种物质在溶液或固相中都是
