are radicals such as hydrogen, halogen and organic radicals such as substituted alkyl. A is a bond or a divalent unit. Y is a chalcogen.
A general and selective palladium-catalyzed alkoxycarbonylation of all kinds of alkenes with formic acid (HCOOH, FA) is described. Terminal, di-, tri-, and tetra-substituted including functionalized olefins are converted into linear esters with high yields and regioselectivity. Key-to-success is the use of specific palladium catalysts containing ligands with built-in base, e.g., L5. Comparison experiments

The complex Tp(Br3)Cu(NCMe) (1) is an excellent catalyst for the regioselective carbene transfer reaction to tertiary C-H bonds of hydrocarbons, at room temperature, using the readily available ethyldiazoacetate (EDA) as the carbene source.

We report quantitative measurements of the relative reactivities of a series of C−H bonds of gaseous or liquid CnH2n+2 alkanes (n=1–8, 29 different C−H bonds) towards in situ generated electrophiles (copper, silver, and rhodium carbenes), with methane as the reference. This strategy surpasses the drawback of previous model reactions of alkanes with strong electrophiles suffering from C−C cleavage processes
我们报告了一系列测量结果,这些测量结果是一系列气态或液态C n H 2 n +2烷烃(n = 1–8,29种不同的C H键)的CH键对原位生成的亲电试剂(铜,银和铑卡宾),并以甲烷为参考。该策略克服了以前的烷烃与强亲电试剂经历C-C裂解过程的模型反应的缺点,该模型无法直接比较烷烃CH键的相对反应性。
