orders of magnitude for every phenol-phosphine oxide base-pair added. These experiments show that the phenylacetylene backbone supports formation of extended duplexes with multiple cooperative intermolecular H-bonding interactions, and together with previous studies on the mixed sequence phenylacetylene 2-mer, suggest that this supramolecular architecture is a promising candidate for the development of
The palladium‐catalyzed C−H oxidation of simple arenes is an attractive strategy to obtain phenols, which have many applications in the fine chemicals industry. Although some advances have been made in this research area, low reactivity and selectivity are, in general, observed. This report describes a new catalytic system for the efficient C−H acetoxylation of simple arenes based on Pd(OAc)2 and a

design and self-assembly of novel cavity-cored metallodendrimers via noncovalent interactions are described. By employing [G0]-[G3] 120 degrees ditopic donor linkers substituted with Fréchet-type dendrons and appropriate rigid di-Pt(II) acceptor subunits, [G0]-[G3]-rhomboidal metallodendrimers and [G0]-[G3]-hexagonal, "snowflake-shaped" metallodendrimers with well-defined shape and size were prepared
描述了通过非共价相互作用的新型空心金属树枝状聚合物的设计和自组装。通过使用 [G0]-[G3] 120 度双位供体接头取代 Fréchet 型树突和适当的刚性二铂 (II) 受体亚基,[G0]-[G3]-菱形金属树枝状聚合物和 [G0]-[G3]在温和条件下以高产率制备了具有明确形状和大小的六边形“雪花状”金属树枝状聚合物。组件的特点是多核 NMR((1)H 和 (31)P)、质谱(ESI-MS 和 ESI-FT-ICR-MS)和元素分析。同位素分辨质谱数据支持具有菱形和六边形空腔的金属树枝状聚合物的存在,核磁共振数据与所有集合的形成一致。[G0]-和[G1]-菱形金属树枝状大分子的结构通过单晶 X 射线晶体学得到明确证实。使用 MM2 力场模型研究了两种 [G3]-六边形金属树枝状聚合物的形状和大小。

We report an iron-catalyzed general functional group protection method with inexpensive reagents. This environmentally benign process does not use acids or bases, and does not produce waste products. Further purification beyond filtration and evaporation is, in most cases, unnecessary. Free COOH and OHgroups can be protected in a one-pot reaction.
