2-Allyl-substituted furans and thiophenes were efficiently synthesized from organostannyl derivatives as starting materials using Cu(I) as catalyst. The effect of DMF and NMP as solvents are discussed, as well as other solvent and temperature effects.
intermolecular aza‐Wacker‐type reaction was developed. When a readily available olefin was treated with a nitrogen nucleophile in the presence of a Pd‐SPRIX complex and potassium persulfate, allylaminederivatives were obtained with high yield and excellent regioselectivity. The mechanistic studies showed that the reaction followed first‐order dependence on the olefin as well as palladium catalyst, but
Acylaromatic compounds ##STR1## (Q: aromatic compound residue; R: straight, branched or cyclic aliphatic group, aromatic group or araliphatic group) are prepared in high yield by a reaction, in the presence of a boron trifluoride complex catalyst, of an aromatic compound with ##STR2## (X: H, Cl, Br; Y: Cl, Br) or with RCOOH in the presence of (XYCHCO).sub.2 O.
