Stereoselective Azine Formation in the Decomposition of Phenyldiazomethanes

The bimolecular dimerization of phenyldiazomethane (1) and 1-diazo-1-phenylethane (2) to form the corresponding azines (3 and 4) is stereoselective for the E,Z isomer (>95:5 E,Z:E,E).The E,Z isomer can be isolated from the reaction of 2, and it can be observed but not isolated from the reaction of 1.Both (E,Z)-3 and -4 revert thermally to the more stable E,E isomer.The kinetic parameters of this process were determined for (E,Z)-4: Ea = 22.3 kcal/mol, log A = 11.2.The stereoselectivity is accounted for within the context of the accepted mechanism for azine formation via diazo compound dimerization.

Azine synthesis via nitrogen-nitrogen bond formation

Imine anions, generated by reaction of nitriles with organometallic reagents, are dimerized to form symmetrical azines through the use of CuI and t-butyl peroxybenzoate.

COMPLEXES OF CYCLOMALTOHEPTAOSE WITH AROMATIC DIAZO COMPOUNDS: FORMATION AND REACTIONS

Pyrolysis of the relatively stable, solid complexes of cyclomaltoheptaose (β-cyclodextrin) with phenyldiazomethane, 1-diazo-1-phenylethane, and diazo(diphenyl)methane results in degradation of the labile guests.The host matrix exerts "reaction-vessel" and "shape-selectivity" effects upon the reaction pathways of the guests and derivatives.The carbene insertion reaction with the β-cyclodextrin hydroxyl groups is regioselective.

CO-OLIGOMERISATION DE BUTADIENE ET D'HETERODIENES AZOTES CATALYSEE PAR LE NICKEL CONTROLE DE LA SELECTIVITE

Nickel (0) catalysed co-oligomerization of butadiene with heterodienes and hetero-olefins is described.It is shown how the selectivity of these reactions can be controlled by the position of the heteroatom in the heteropartner and also by the nature of th
