Products of the oxidative cleavage of olefmic double bonds are more prevalent during Rh(I)-catalyzed oxidation of cinnamaldehyde [486] and styryl acetate [486] than with styrene itself, equations (294) and (295). 

The Lewis acid-promoted reaction of benzaldehyde with isopropenyl and a-styryl acetates gives acetyl-protected aldols. This aldol reaction is effectively catalyzed by Me3Si[B(C6F5)4] [16]. 

The observed by-products (tert-butyl ether and the compound resulting from the dimerization of the diphenylmethane) seem to support a radical mechanism (Scheme 4.18). Firstly, the benzylic radical intermediate and the BuO radical 18-A, generated via an SET process, undergo an electrophilic addition to styryl acetate leading to an iron-coordinated radical intermediate 18-B. The latter, after decomposition of the intermediate 18-C, leads to the desired product, AcO Bu, and re-generates the iron catalytic species.

Aliphatic and aromatic aldehydes condensed with 2-amino-(62BRP898414), 5-amino- (80AJC1147), or 8-amino-l,2,4-triazolo[l,5-cjpyrimidines (68JOC530) to give the related Schiff bases. Treatment of the 2-amino-5-methyl-l,2,4-triazolo[l,5-c]quinazoline 11 with formaldehyde and piperidine in the presence of acetic acid gave the 2-hydroxymethyl-amino-5-(2-piperidinoethyl) derivative 172. Utilization of aromatic aldehydes and piperidine in this reaction gave the 2-arylideneamino-5-styryl derivatives 173 (68CB2106) (Scheme 67). 

Triazinethiones have been used frequently for the syntheses of triazino-triazines in the literature. Reaction of 6-methyl-5-[substituted styryl]-2/7-[l,2,4]triazine-3-thiones 39 with thiourea or acetylthiourea in dimethylformamide (DMF) led to the formation of N,N -disubstituted thioureas 40. Heating the compound 40b with glacial acetic acid and fused sodium acetate under reflux led to the formation of the compounds 4,7-dimethyl-8-[2-ethenylfuran]-2-thioxo-l,3,5-triazino[5,6- ][l,2,4]triazine 22 (Scheme 6) <2003PS279>. 

Uncharged styryl (methine) disperse dyes were originally introduced to provide greenish yellow colours on cellulose acetate fibres. One such dye still in use is Cl Disperse Yellow 31 (6.226), which is made by condensing 4-(N-butyl-N-chloroethylamino)benzaldehyde with ethyl cyanoacetate. Suitable compounds for polyester usually contain the electron-accepting dicyanovinyl group, introduced with the aid of malononitrile. An increased molecular size leads to improved fastness to sublimation, as in the case of Cl Disperse Yellow 99 (6.227). A novel polymethine-type structure of great interest is present in Cl Disperse Blue 354 (6.228), which is claimed to be the most brilliant blue disperse dye currently available [85]. 

Benzofuran in boiling dioxane and acetic acid, in the presence of equimolar proportions of styrene and palladium(II) aeetate, yields 2,3-diphenyl-dibenzofuran (26%) as well as 2-styryl- (16%) and 3-styrylbenzofuran (3%). The reaction presumably involves electrophilic substitution at the 2-position of benzofuran by palladium(II) acetate, followed by addition to the alkene and loss of palladium hydride. Further reaction at the 3-position of the resultant 2-styrylbenzofuran would yield an intermediate that could undergo... 

Treatment of the pyrazolium[4,3-r/][l,2,3]oxadiazolium diiodide 124 with -hydroxy- or /)-dimethylaminobenzalde-hyde yielded the pyrazolo[4,3-r/][l,2,3]oxadiazole styryl and azastyryl cyanines 83a and 83b in modest yields. Parallel reaction with -nitrosophenol furnished 83c. Reaction of 124 with 1-ethylquinolinium iodide afforded 84a directly. However, 3-anilinocarbomylmethyl-2,4-diethyl-(N-phenylcarbomylmethyl)pyrazolium(4,3-r/)[l,2,3]oxadiazolium diiodide 125 arising from reaction of 124 with diphenylformamidine in refluxing acetic anhydride, is the precursor to 84b which follows from subsequent reaction with 2-methylisoquinolinium iodide (Scheme 16) <1994MI905-1>. 

The condensation of the 1-methyl group in 2-benzopyrylium salts 92 with carbonyl derivatives such as aromatic aldehydes (70KGS1308) in acetic acid gives rise to 1-styryl-substituted salts 94. The reaction proceeds similarly with orthoesters (74KGS37), isocoumarin derivatives, and di-methylformamide (DMF) (80KGS193) or azomethines (82KGS465). The... 

The styryl iodonium salt (7 a) reacts slowly with acetic acid to give the E and Z isomeric products (8a) and (9a) in the ratio 85 15.3 The decenyl system (7b) is much more reactive and gives only the inversion product, the Z isomer (9b). It was suggested that the styryl system reacts in a two-step mechanism via the vinylene phenonium ion (10), whereas the decenyl system follows a one-step vinylic. S n2 mechanism, hi contrast, 2-bromo-l-decenyliodonium salt reacts with bromide ion in MeCN with complete retention.4 The observed rate constants show an unexpected dependence on [Br ], in accordance with a mechanism involving ligand coupling within a bromoiodane intermediate.

One method for the synthesis of hydroxyalkyl-substituted P-lactams is by the Staudinger reaction, the most frequently used method for the synthesis of P-lactams.86 This method for the preparation of 4-acetoxy- and 4-formyl-substituted P-lactams involves the use of diazoketones prepared from amino acids. These diazoketones are precursors for ketenes, in a diastereoselective, photochemically induced reaction to produce exclusively tram-substituted P-lactams. The use of cinnamaldimines 96, considered as vinylogous benzaldimines, resulted in the formation of styryl-substituted P-lactams. Ozonolysis, followed by reductive workup with dimethyl sulfide, led to the formation of the aldehyde 97, whereas addition of trimethyl orthoformate permitted the production of the dimethyl acetal 98 (Scheme 11.26).
