Size effect of silver nano particles on the photophysical properties of 2,3-bis(chloromethyl)anthracene-1,4,9,10-tetraone (BCMAT) have been investigated using optical absorption and fluorescence emission techniques. Silver NPs of different sizes have been prepared by two different methods. Quenching of fluorescence of BCMAT has been found to increase with decrease in the size of the silver NPs. Stern-Volmer quenching constants have also been calculated.

The ortho-anthraquinonedimethane dienophiles prepared in situ from 1,4-dihydroxy-2,3-bis(bromomethyl)-anthraquinone and 1,4-dimethoxy-2,3-bis(bromomethyl)anthraquinone respectively react with the fullerene C60 to give the anthraquinone derivatives: dihydroxy-anthraquinone-C60 and dimethoxy-anthraquinone-C60. The former compound with sodium butoxide and 15-crown-5 gives the bis(sodium-15-crown-5)dioxo-anthraquinone-C60. The dimethoxy-anthraquinone-C60 reacts with [Ru(PPh3)2(NO)Cl] to form the bis-adduct {[η2-(dimethoxy-anthraquinone-C60)][Ru(PPh3 )2(NO)Cl]}. The electrochemistry of the dihydroxy- and dimethoxy-anthraquinone-C60 derivatives has been studied by cyclic voltammetry and, in contrast to 1,4-dihydroxy-2,3-dimethylanthraquinone, the compound dihydroxy-anthraquinone-C60 shows two separate one electron oxidations at lower potentials strongly suggesting a relatively rare example of a fullerene stablised cation.

Biacetyl has been converted into a series of 3-(acyloxy)-3-buten-2-ones (13-17) which were characterized both spectroscopically and as their crystalline adducts with 1,3-diphenylisobenzofuran.A comparative study has been made of the reaction of these dien

The anthracycline antibiotics daunorubicin and adriamycin are important clinically useful drugs in the treatment of a number of human cancers.The structurally simplified synthetic analogues 4-demethoxydaunorubicin and 4-demethoxyadriamycin show much clinical promise.The synthesis of the corresponding aglycon (+/-)-4-demethoxydaunomycinone from the inexpensive dye intermediate quinizarin, utilizing o-quinodimethane intermediates, is discussed.
