A variety of terminal arylacetylenes have been conveniently synthesised in good to high yields by Stille coupling of aryl halides with ethynyltributylstannane catalysed by a MCM-41-supported bidentate phosphine palladium(O) complex in an aqueous medium and under air. Our system not only avoids the requirement for water-free and oxygen-free conditions, but also solves the basic problem of palladium catalyst reuse.

An efficient heterogeneous palladium(0)-catalysed cross-coupling of 1-bromoalkynes with terminal alkynes was achieved in DMF at room temperature in the presence of 5 mol% of MCM-41-immobilised bidentate phosphine palladium(0) complex [MCM-41-2P-Pd(0)] and 2 mol% of CuI with Et3N as base, yielding a variety of unsymmetrical 1,3-diynes in moderate to good yields. This heterogeneous palladium(0) complex could be easily recovered by a simple filtration of the reaction solution and recycled at least seven times without significant decrease in activity.

<div>While carbon-heteroatom cross coupling reactions have been extensively studied, many methods are specific and</div><div>limited to a set of substrates or functional groups. Reported here is a method that allows for C-O, C-N and C-S cross coupling reactions under one general methodology. We propose that an energy transfer pathway, in which an iridium photosensitizer produces an excited nickel (II) complex, is responsible for the key reductive elimination step that couples aryl halides to 1° and 2° alcohols, anilines, thiophenols, carbamates and sulfonamides.</div>
