A highly efficient palladium-catalyzed Sonogashira coupling of benzylic ammonium salts with terminal alkynes is developed. This strategy provides a facile access to a series of internal alkyne derivatives in moderate to excellent yields via C-N bond cleavage and C(sp3)-C(sp) bond formation. The broad substrate scope and high functional group tolerance make this reaction attractive for organic synthesis.

experimental part, p. 1126 - 1129 (2009/09/25)
A new procedure has been developed for aminomethylation of terminal acetylenes with N,N,N′,N′-tetramethylmethanediamine in the presence of transition metals and lanthanide complexes and salts. The procedure ensures formation of the corresponding N,N-dimethylprop-2-yn-1-amines with high yield and selectivity.
Photosensitized Oxidation of Furans. Part 12. Solvent Effects in Thermal Rearrangement of the 2,5-Peroxides of 2,5-Unsubstituted Furans

The formation, thermal stability, and modes of thermal rearrangement of the 2,5-peroxides (1a-i) of 2,5-unsubstituted furans are reported.In apolar solvents the main product of thermal rearrangement is the cis diepoxide (3) accompanied by the epoxyfuranones (6) and (7).These rearrangements are thought to proceed via concerted processes, although no distinction can be made between them and rearrangements via diradicals.In basic solvents the 5-hydroxyfuran-2(5H)-ones (4) and (5) are isolated in high yields.In this case the rearrangements are explained by assuming ion pairs, (18), as intermediates.
