catalyst in combination with either a stoichiometric amount of Brønsted acid or a catalytic amount of Lewis acid is capable of catalyzingregioselective alkylation of N‐heteroarenes with N‐(acyloxy)phthalimides at room temperature under irradiation. A broad range of N‐heteroarenes can be alkylated using a variety of secondary, tertiary, and quaternary carboxylates. Mechanistic studies suggest that an IrII/IrIII
铱光氧化还原催化剂与化学计量的布朗斯台德酸或催化量的路易斯酸结合使用,能够在室温下于辐射下催化N-(酰氧基)邻苯二甲酰亚胺对N-杂芳烃的区域选择性烷基化。可以使用各种仲,叔和季羧酸盐将多种N-杂芳烃烷基化。机理研究表明,Ir II / Ir III氧化还原催化循环是所观察到的反应性的原因。

Described herein are silicon based conjugates capable of delivering one or more payload moieties to a target cell or tissue. Contemplated conjugates may include a silicon-heteroatom core, one or more optional catalytic moieties, a targeting moiety that permits accumulation of the conjugate within a target cell or tissue, one or more payload moieties (e.g., a therapeutic agent or imaging agent), and two or more non-interfering moieties covalently bound to the silicon-heteroatom core.
