So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Skauge, Andrew R. L.; Shalders, Richard D.; Swaddle, Thomas W. researched the compound: Diiodo(1,5-cyclooctadiene)platinum(II)( cas:12266-72-7 ).Application of 12266-72-7.They published the article 《High-pressure methods as a tool in organometallic syntheses: facilitation of oxidative addition to platinum(II)》 about this compound( cas:12266-72-7 ) in Canadian Journal of Chemistry. Keywords: high pressure oxidative addition platinum; alkyl iodide oxidative addition platinum pressure; volume activation oxidative addition platinum. We’ll tell you more about this compound (cas:12266-72-7).
High-pressure (2 GPa) batch reactors now com. available may offer substantial accelerations of organometallic syntheses, without resort to heating, when the activation process is multicentered or involves the generation and solvation of ions. As an example of the latter class of reactions, the kinetics of the oxidative additions of Me and Et iodides (RI) to dimethyl(2,2′-bipyridine)platinum(II) in acetone were studied over the pressure range 0-200 MPa. The volumes of activation ΔV1⧧, if assumed to be constant over this range, are -11.7 ± 0.3 and -9.7 ± 0.7 cm3 mol-1, resp., implying an acceleration of ∼3000-fold for a batch synthesis of this sort at 2 GPa. However, a possible slight pressure dependence of ΔV1⧧ may reduce this acceleration to ∼1,000-fold. The ΔV1⧧ data and the 500-fold retardation on going from R = Me to R = Et are consistent with an SN2 attack of PtII on the α-C in the alkyl iodides, forming I- and [RMe2Pt(bpy)]+.
