Direct carboxylation of simple arenes under atmospheric pressure of CO2 is achieved through a rhodium-catalyzed C-H bond activation without the assistance of a directing group. Various arenes such as benzene, toluene, xylene, electron-rich or electron-deficient benzene derivatives, and heteroaromatics are directly carboxylated with high TONs. This journal is

Figure Presented Pump it up! The sluggish reactivity of organozinc reagents in additions to aldehydes, ketones, and CO2 can be increased by MgCl2, which is usually generated in the preparation of the zinc reagent. The direct reaction with CO2, in particular, opens an expeditious route to phenylacetic acid derivatives, as demonstrated in a short synthesis of ibuprofen (see scheme).

Model reactions targeted at the synthesis of carbon-14 labeled CI-996, a potent antagonist of angiotensin II receptor (1)
Ekhato,Huang
, p. 213 - 220 (2007/10/02)
A reaction sequence suitable for the preparation of an analog of 2-propyl-1-[[2'-(1H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl]methyl-4-[2-(tr ifluoroacetyl)-1H-pyrrol-1-yl]-1H-imidazole-5-carboxylic acid, with 14C at the methylene bridge was developed. The would-be labeled fragment (12) was derived from 4-iodobenzenemethanol (6) which itself was constructed from 1,4-dibromobenzene by the application of silicon chemistry. Pd(o) catalyzed coupling of TBDMS protected 6 and a tetrazole borate 10 gave the compound 12 which upon further transformation to the mesylate 13, N-alkylated an imidazole to furnish target compound.
