A general and practical synthetic method for the construction of unsymmetrically substituted diphenyldiazenes based on classical azo coupling reaction has been developed. A key feature of this method is the use of N,N-diallyl protected aniline derivatives

An easy and rapid procedure for the preparation of a variety of mono- and bis-allylated anilines via the reaction of allyl bromide with a wide range of anilines under microwave irradiation is described. This approach allows use of mild conditions and short reaction times to give high selectivities and excellent yields.

An assisted tandem catalytic transformation of diallyl amines and diallyl ethers into N-aryl pyrroles and furans, respectively, is described. The sequence relies on ring closing metathesis followed by dehydrogenation of the initially formed dihydropyrroles and dihydrofurans. Both steps are Ru-catalyzed, but the sequence requires only one precatalyst, because conversion of the metathesis catalyst into the dehydrogenation catalyst is achieved in situ, triggered by the oxidant tert-butyl hydroperoxide.
Synthesis of heterocyclic compounds by ring-closing metathesis (RCM): Preparation of oxygenated or nitrogenated compounds
Sanchez, Isabel,Pujol, Maria Dolors

Novel methods for heterocyclic synthesis by metathesis have been developed. Versatile heterocyclic compounds were easily prepared in good yield from intermediate olefins by ring-closing olefin metathesis using the catalyst dichloro(benzylidene)bis(tricycl
