The visible-light-driven preparation of (hetero)aryl stannanes was carried out under both photocatalyst- and metal-free conditions via irradiation of arylazo sulfones in the presence of hexaalkyldistannanes. The reaction shows a high efficiency and a wide substrates scope. The resulting crude organotin derivatives can be directly employed in a Stille protocol.

(PDGF-RTK) activity. The compounds were generally prepared either by a Friedlander condensation between an aryl-acetaldehyde and an o-aminobenzaldehyde or by a palladium-catalyzedcoupling between an aryl bromide or triflate and an organostannane or organozinc chloride. The presence of 6,7-dimethoxy groups on the quinoline ring was found to be advantageous although not essential for potent inhibition

of arylstannanes have been synthesized, through an SRN1mechanism, in good to excellent yields (74%–99%) by the photostimulated reaction of trimethyl stannyl ion with substrates supporting different nucleofugal groups. The arylstannanes thus obtained were suitable intermediates for Stille cross-coupling reactions leading to asymmetric bi- and triaryl compounds in acceptable global yields. An attractive
A Practical Method for the Preparation of 18F-Labeled Aromatic Amino Acids from Nucleophilic [18F]Fluoride and Stannyl Precursors for Electrophilic Radiohalogenation
for the synthesis of 18F-labeled aromatic amino acids from additionally N-Boc protected commercially available stannyl precursors routinely applied for electrophilic radiohalogenation. Finally, an automated synthesis of 6-[18F]fluoro-l-m-tyrosine (6-[18F]FMT), 2-[18F]fluoro-l-tyrosine (2-[18F]F-Tyr), 6-[18F]fluoro-l-3,4-dihydroxyphenylalanine (6-[18F]FDOPA) and 3-O-methyl-6-[18F]FDOPA ([18F]OMFD) was

Complexes cis-[PtR2(dmso)2] and cis-[PtRCl(dmso)2](dmso = dimethyl sulphoxide) are readily obtained from K2[PtCl4] and SnMe3R (R = aryl or Me) in dmso at 70–90 °C. Hydrogen-1 n.m.r. spectra show that the dmso ligands are bound through sulphur in solution and that the dmso ligand trans to R in cis-[PtRCl(dmso)2] undergoes dissociation and exchange at ambient temperature.
