Phenylacrylic acid

Alkenylmercury compounds are coupled to give conjugated dienes by the transmetallation with Pd(II). A mixture of ( )- and (Z)-dibenzylidenesuccinic acids (451 and 452) was obtained by the transmetallation of 2-chloromercurio-3-phenylacrylic acid (450) with Li2PdCl4 in the presence of CuCl2[409,410], III6-6...

Reaction of l-aryl-3-carbethoxy-6-phenyl-l,4,5,6-tetrahydropyridazin-4-ones 718 with activated olefins such as benzalacetophenone, benzalacetone, 3-benzylideneacetylacetone, diethyl 2-benzylidenemalonate, and a-cyano-/3-phenylacrylic acid in the presence of an organic base like pyrrolidine, morpholine, piperidine, or triethylamine gave the corresponding 2,8-dihydro-l//-pyrano[2,3-t7 pyridazines 719-723, respectively. The 1-oxo- and 1-imino derivatives of the pyrano[2,3-r/ pyridazine ring system were also prepared from the respective 6-oxo or 6-imino derivative of the starting pyridazine 718 under the same conditions (Equation 60) <1989IJB733>.

To understand why solution experiments sometimes fail to produce cocrystal products, and why solvent-drop grinding experiments can work when performed on the same system, the 1 1 cocrystal formed by nicotinamide and frans-cinnamic acid (frans-(2E)-3-phenylacrylic acid) has been studied [56]. In this work ternary isothermal phase diagrams of the cocrystal system was used to understand the crystallization phenomena, and to deduce methodologies and for the experimental design of cocrystal preparation. Cocrystals are most likely to form from solutions in which the two reactants have similar degrees of solubility, and the success of solvent-drop grinding was explained in that crystallization took place in the region of low solvent mole fractions where the cocrystal would be more stable relative to the separated reactants. 

A. Esterification of a-Cyano-fi-Phenylacrylic Acid — In a 200-cc. round-bottom flask fitted with a reflux condenser, 50 g. of dry a-cyano/3-phenylacrylic acid (Org. Syn. 7, 20) is boiled for four and a half hours with 100 cc. of absolute alcohol containing 3-4 g. of anhydrous hydrogen chloride. The resulting solution is filtered rapidly while hot and allowed to stand overnight. Long, flat, colorless prisms separate which are filtered off with suction, washed with a little cold alcohol and dried in air. A further small quantity may be obtained by working up the mother liquor. The melting-point of the ethyl a-cyano-jS-phenylacrylate is 50 0 and the yield 46.5-53 g. (82-94 per cent of the theoretical amount).

The BINAP-Rh -catalyzed hydrogenation of enamide 2-acetylamino-3-phenylacrylic acid was studied using the hybrid IMOMM QM/MM method [58]. It was found that the relative energy differences between diastereomers (14-PRO-/ and 14-PRO-5) in both the oxidative addition and migratory insertion steps are consistent with the experimentally observed enantioselectivity. This theoretical evidence shows a shift for this particular ligand-substrate combination as well as the hydrogenation of a-acylaminoacrylates by [Rh((S,S)-dipamp)] to a lock-and-key motif (Scheme 6).
