Decarboxylative Hydroxylation of Benzoic Acids [PDF]
Angewandte Chemie, 2021 AbstractHerein, we report the first decarboxylative hydroxylation to synthesize phenols from benzoic acids at 35 °C via photoinduced ligand‐to‐metal charge transfer (LMCT)‐enabled radical decarboxylative carbometalation. The aromatic decarboxylative hydroxylation is synthetically promising due to its mild conditions, broad substrate scope, and late ...

4-(Diphenylphosphanyl)benzoic acid [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title compound, C(19)H(15)O(2)P, the dihedral angles between the benzoic acid ring and the phenyl rings are 75.64 (7) and 80.88 (7)°; the dihedral angle between the phenyl rings is 81.35 (7)°. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops between the head-to-head carb-oxy-lic acid groups.

2-(Trifluoromethyl)benzoic acid [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 In the title compound, C(8)H(5)F(3)O(2), a halogenated derivative of benzoic acid, the carboxyl group is tilted by 16.8 (3)° with respect to the plane of the aromatic ring. In the crystal, O-H⋯O hydrogen bonding gives rise to carb-oxy-lic acid dimers, which are further connected into double chains along [1,1/4,1] by C-H⋯O contacts.

2-(Acetoxymethyl)benzoic acid [PDF]
Acta Crystallographica Section E Structure Reports Online, 2013 The title compound, C10H10O4, crystallizes with the well-known carboxylic acid dimer-formingR22(8) hydrogen-bond motif. Chains approximately parallel to (-1-12) are then built through C(methylene,phenyl)–H...O(carbonyl) interactions [C(6) andC(8) motifs] with one (methyl)C—H...π interaction providing interplanar binding.
