The use of 2-(trimethylsilylethyl)sulfonamide (SES-NH2) has permitted the selective and efficient synthesis of new triolefinic 15-membered azamacrocycles 3. Differential coordination mode with palladium has been observed when macrocycle 3aab [(E,E,E)-1,6-bis(p-tolylsulfonyl)-1,6,11-triazacyclopentadeca-3,8,13-triene] was treated with a palladium(0) or a palladium(II) source.
2-(三甲基甲硅烷基乙基)磺酰胺(SES-NH 2)的使用已允许新的三烯烃15元氮杂大环3的选择性和有效合成。当大环3aab [(E,E,E)-1,6-双(对甲苯磺酰基)-1,6,11-三氮杂环戊adeca-3,8,13-三烯]处理后,观察到与钯的差异配位模式。钯(0)或钯(II)源。
