    Highly Regioselective α-Chlorination of the BODIPY Chromophore with Copper(II) Chloride
    摘要:
    A general and efficient method for a-chlorination of 4,4'-difluoro-4-bora-3a,4a-diaza-s-indacenes (BODIPYs) has been developed using CuCl2 as chlorination reagent. The reaction is characterized by complete 3/5-positions of BODIPY regioselectivity. This unusual highly regioselective alpha-halogenation of BODIPY is in sharp contrast to previously reported halogenation methods which preferred to occur first at the 2,6-positions of BODIPY. This approach provides a straightforward, facile, and economical route to 3- and/or 5-chloroBODIPYs with various meso-groups (H, alkyl, and aryl) and their derivatives.

  • Metal-Free Direct α-Selective Arylation of Boron Dipyrromethenes via Base-Mediated C–H Functionalization

    A metal-free direct α-selective arylation of BODIPYs has been developed based on base-mediated C–H functionalization with easily accessible diaryliodonium salts, which provides a straightforward facile access to a variety of α-arylBODIPY dyes. The α-regioselectivity was confirmed by X-ray analysis, and was studied by DFT calculation. The resultant dyes show strong absorption and emission over a broad

    with sodium sulfinates via a radical process is described for the first time. This transformation presented wide substrate scope and high regioselectivity, providing a series of α-sulfonylated BODIPYs. Meaningfully, the sulfonyl group, as a good leaving group, allowed the facile introduction of a variety of functionalities on the BODIPY core. Moreover, a 2,4-dinitrobenzenesulfonyl (DBS) group substituted

    cross-dehydrogenative coupling of BODIPYs with toluene and its derivatives has been developed, allowing for the facile synthesis of a broad range of structurally diverse α-benzylated BODIPYs. The method exhibits excellent chemoselectivity, affording exclusively α-benzylated BODIPYs in the presence of t-BuOOH and a catalytic amount of Cu(OAc)2. The direct use of readily available toluene and its derivatives as coupling
    已经开发了BODIPY与甲苯及其衍生物的氧化交叉脱氢偶联,可轻松合成各种结构多样的α-苄基BODIPY。该方法表现出优异的化学选择性,在存在t- BuOOH和催化量的Cu(OAc)2的情况下,仅提供α-苄基化的BODIPYs 。直接使用容易获得的甲苯及其衍生物作为偶联伙伴可避免用于预活化官能团安装的非生产性步骤,因此具有吸引力。由于将大体积的苄基引入到BODIPY核上,大多数所得染料在固态时具有高发射率。

    Regioselective and stepwise syntheses of a series of functionalized BODIPY dyes through palladium-catalyzed cross-coupling reactions and direct C–H arylations have been developed. In particular, this method allows the straightforward synthesis of 2,6-dibromo-3,5-diarylBODIPYs and 2-bromo-3-arylBODIPYs from polybrominated BODIPYs. The X-ray structure of intermediates 5a–c indicated that the palladium
