[PdCl(1a)]2 reacts with CH2CHCO2CH2CH3 to afford 2′(CHCHCO2CH2CH3)-5′-OCH3C6H3CHO, and [Pd(μ-OAc)(1a)]2 with I2 to give 2′-I-5′-OCH3C6H3CHO. Excess CH3O2CCCCO2CH3 reacts with various substituted cyclopalladated Schiff's bases in MeOH to afford which we formulate as possessing two PdC bonds, and one coordinated ester O atom. The X-ray crystal structure of [Pd(μ-OAc)(1a)]2 has been determined; relevant bond
2'-环钯酸的亚胺配合物与甲醇在MeOH中反应生成2'-取代的芳基亚胺2'-CO 2 CH 3 -5'-OCH 3 C 6 H 3 CHNTol(Tol = C 6 H 4 -4- CH 3)。该反应的产物可以通过将桥接配体从AcO改变为Cl来改变,在这种情况下,仅获得5元环杂环化合物。[Pd(μ-OAc)(1a)] 2具有2当量。Ph 3 P和CO(1 atm)的摩尔数表示杂环是由两个CO插入反应引起的,而[PdX(1a)] 2(X = AcO,Cl),当量为4。CNBu t的数量和4个当量 的Ph 2 PCH 2 CH 2 PPh 2生成杂环烯酮亚胺[PdCl(1a)] 2与CH 2 CHCO 2 CH 2 CH 3反应,得到2'(CHCHCO 2 CH 2 CH 3)-5' -OCH 3 C 6 H 3 CHO和[Pd(μ-OAc)(1a)] 2与I 2给出2'-I-5'-OCH 3
