trans-(DMPE)(2)Ru(H)(NH(2)) (1) dehydrogenates cyclohexadiene and 9,10-dihydroanthracene to yield benzene (or anthracene), (DMPE)(2)Ru(H)(2), and ammonia. Addition of fluorene to 1 results in the formation of the ion pair [trans-(DMPE)(2)Ru(H)(NH(3))(+)][A(-)] (A(-) = fluorenide, 4a). Complex 1 also reacts with weak acids A-H (A-H = phenylacetylene, 1,2-propadiene, phenylacetonitrile, 4-(alpha,...
Both (19)F MRI and optical imaging are powerful noninvasive molecular imaging modalities in biomedical applications. To integrate these two complementary imaging modalities, the design and synthesis of a novel (19)F MRI/fluorescence dual-modal imaging agent is reported herein. Through Sonogashira coupling reaction between the fluorinated phenylacetylene and 1,2,4,5-tetraiodobenzene, a fluoropho...
Platinum nanoparticles (PtNP) either imbedded within (PtNP@GNF) or adsorbed on the surface (PtNP/GNF) of hollow graphitised carbon nanofibres catalyse hydrosilylation reactions inside or outside the nanoreactor respectively. Comparison of the products formed using PtNP@GNF and PtNP/GNF reveals that nanoreactors create an environment promoting the formation of aromatic over aliphatic products in...
