The experimental procedures were essentially the same as reported (Figure 1, (16, 17)). Reagents other than those described in (16. 17) were as follows. Acrylic acid(Wako Pure Chemicals) was distilled once under reduced pressure under a nitrogen stream. Solvents(acetonitrile, n-hexane, and benzene) were purified by accepted procedures. 

In accordance with the suggested mechanism aryl iodides react easily (Scheme 6.2). At 80-100 °C, iodobenzene and acrylic acid gave cinnamic acid in neat water with [Pd(OAc)2] as catalyst and a mix of NaHCOs and K2CO3 as base [12]. Similar reactions were mn in water/acetonitrile 1/1 with... 

Acrylate 96 was acylated with acetyl chloride to deliver the acetate 97 in 98% yield (Scheme 4.16). C-Acylation of 97 was achieved at the (3-position of the acrylate in the presence of triethylamine in acetonitrile with acid chlorides 98a and 98b gave benzoylacry-lates 99a and 99b in 91% and 66% yield, respectively. 

Block copolymers of vinyl acetate with methyl methacrylate, acrylic acid, acrylonitrile, and vinyl pyrrolidinone have been prepared by copolymerization in viscous conditions, with solvents that are poor solvents for the vinyl acetate macroradical (123). Similady, the copolymerization of vinyl acetate with methyl methacrylate is enhanced by the solvents acetonitrile and acetone and is decreased by propanol (124). Copolymers of vinyl acetate containing cyclic functional groups in the polymer chain have been prepared by copolymerization of vinyl acetate with IV,IV- diallylcyan amide and N,N-diallylamine (125,126).

Fig. 1 Isocratic electrochromatography of peptides in a capillary filled with a macroporous polyacrylamide-polyethylene glycol matrix, derivatized with a C12 ligand (29%) and containing acrylic acid. Conditions mobile phase, 47% acetonitrile in a buffer voltage, 22.5kV (900 V/cm), 7 [jim sample concentration, 4-10 mg/mL detection, UV absorbance at 270 nm other conditions are described in Ref. 5.

Propylene ammoxidation experiments were conducted using a single pass, plug flow, tubular (3/8 ) stainless steel reactor operated at atmospheric pressure at 420°C. The gaseous feed mixture consisted of propylene, ammonia, air and water in the ratios 1/1.2/10.5/4. Liquid products were collected in an aqueous scubber and analyzed for acylonitrile, acrylic acid and acetonitrile via gas chromatography, NH.. and HCN via titration. Nonsoluble gases were collected and analyzed via gas chromatography. 

PPy may be similarly coated on low-density polyethylene (LDPE), whereas grafting of the LPDE surface with acrylic acid enhances film growth and adhesion.86 The in situ oxidation of pyrrole by Fe(III) can also be used to deposit PPy films on polystyrene substrates.87 In a variation of this method, polyimide films exhaustively soaked in pyrrole (with up to 14% monomer uptake) have been coated with PPy via oxidation with FeCl3 in acetonitrile solvent.88 The resultant material shows electrical conductivity of ca. 4 x 10 2 S cm-1. 

Further investigations by Jeffery indicated the rate- and selectivity-enhancing ability of tetraalkylammonium salts in Heck-type reactions [7]. In particular, tetra-butylammonium chloride, bromide and hydrogensulfate are extensively applied in aqueous DMF and acetonitrile, resulting in the fast and clean conversion of phenyl iodide with acrylic acid in 96% yield. 

The second method was based on a cycloaddition reaction of olefinic and acetylenic dipolarophiles to xanthinium-(N7) ylides. Xanthinium-(N7) ylides 22 were generated from 7-substituted 1,3,9-trimethylxanthinium tosylates 21 by deprotonation with triethylamine in dry acetonitrile followed by reaction with dipolarophiles 23 and 25 (dimethyl fumarate, fumaronitrile, methyl acrylate, acrylonitrile and the like). Reaction with dimethyl fumarate afforded the endo-(24a) and exo-(24b) adducts in a 3 2 ratio. The stereochemistry of these compounds was established by H-NMR and X-ray analysis (84H2199). With derivatives of acrylic acid 25, only endo adducts (26)...
