A series of subporphyrin-based fluorescent probes bearing 1-aza-15-crown-5 or 1-aza-18-crown-6 moieties at the meso axial positions were prepared by Pd-catalyzed Buchwald-Hartwig amination reaction corresponding bromosubporphyrins. Both types aza-crown-ether-incorporated subporphyrins in solution and exhibited cation-dependent absorption fluorescence changes. In titration experiments, opposite ...

and indeed many of the other analyses reported in our paper do not suffer from potential bias due to weak instruments. Hartwig and Davies did, however, suggest that we could have used estimates from an external source to obtain less biased results in our MR-Egger analyses. Whereas we agree that this would be good practice in most situations, we do not feel that it would have been appropriate in...

A systematic study of heterogeneous Buchwald-Hartwig amination using shape-controlled Pd nanocrystals with distinctly different surface facets is presented.

N-Alkoxycarbonyl / carbamoylmethyl substituted 1H-imidazol-2-yliden-Pd (II) complexes (Cat-1-5) were used for the first time as catalysts in Suzuki-Miyaura reaction between aryl bromides and arylboronic acids. All screened found to be excellent selected coupling 4-bromobenzaldehyde phenylboronic acid at room temperature. Cat-3 was shown most efficient one optimisation of conditions determining ...
