The X-ray structure of tetraiodoallene is reported. On standing, atmospheric hydrolysis converts this compound into 2,2-diiodoacrylic acid, for which a structure has also been determined. Energy framework diagrams have been constructed for the two co

In order to get insight into transmission mechanisms of the title spin–spin coupling constants, nJ(C, F1) couplings (n = 4, 5) were calculated at the DFT-B3LYP-6-311-G**/EPR-III level, and couplings were measured in 9 members of the series 1-F,4-X-

Publikováno v: Journal of the American Chemical Society. 126:10778-10786
The electron-transfer rate constant is measured in two U-shaped donor-bridge-acceptor molecules over a wide range of temperature in acetonitrile and N-methylacetamide (NMA). The electron-transfer rate at high temperature can be well described by a no

Synthesis and photophysical studies of a porphyrin–viologen dyad covalently linked by a flexible seven-atom chain

A dyad with terminal porphyrin (P) and viologen (MV 2C ) chromophores covalently linked by a flexible seven-atom hexanoate chain has been synthesized. Ab initio and semi-empirical solvent continuum calculations suggest that the preference for ‘exte

Publikováno v: Angewandte Chemie International Edition. 38:3219-3222
A solution to the vexing problem of investigating solvent-mediated electron transfer under conditions of frozen solvent motion may be at hand with the synthesis of novel U-shaped systems such as 1 (R=CO(2)Me) and 2 (R=CH(2)OMe), in which the imide-fu
