A straightforward and effective procedure for the conversion of benzylic, allylic and aliphatic alcohols to the corresponding iodides using Ph3P/I2 under solvent-free conditions using microwaveirradiation is reported.
据报道,在无溶剂条件下,使用微波辐照,使用Ph 3 P / I 2将苄基,烯丙基和脂族醇转化为相应的碘化物,是一种简单有效的方法。

The first example of UV light-induced, copper-catalyzed regio- and stereoselective decarboxylative coupling of α,β-unsaturated acids with alkyl iodides was reported. Under standard conditions, the 1°, 2°, and 3° alkyl iodides proceeded smoothly with the E-selective alkenes obtained in uniformly good yields and high stereoselectivities.
A metal‐free radical borylation of alkyl and aryl iodides with bis(catecholato)diboron (B2cat2) as the boron source under mild conditions is introduced. The borylation reaction is operationally easy to conduct and shows high functional group tolerance and broad substrate scope. Radical clock experiments and density functional theory calculations provide insights into the mechanism and rate constants
介绍了在温和条件下以双(儿茶酚)二硼(B 2 cat 2 )作为硼源对烷基碘化物和芳基碘化物进行金属自由基硼化反应。硼化反应操作简便,具有较高的官能团耐受性和广泛的底物范围。自由基时钟实验和密度泛函理论计算提供了对 B 2 cat 2的 C 自由基硼化的机制和速率常数的见解。

日期:——
The direct functionalisation of alkanes through bromination and iodination has been successfully achieved. The combination of stoichiometric mixtures of elemental halogen and sodium alkoxides leads to the formation of alkyl hypobromites and hypoiodites as reagents. The halogenation occurs without external photostimulation under thermal reaction conditions.
