Ethylene derivatives esters

Ch1orocarhony1trime11itic acid 1,2-anhydride [1204-28-0] (9), is used in the preparation of esters and amide—imide polymers. TriaHyl trimellitate [2694-54-4] (10) is used as a cross-linking or co-curing agent for ethylene-derived mbbers and plastics. [Pg.498]

In addition to the reactions mentioned, ethyl diazoacetate takes part in many condensations with acetylene and ethylene derivatives, when the nitrogen is retained in the molecule. Thus, with esters of fumaric acid, for example, pyrazoline tricarboxylic esters are produced ... [Pg.280]

In Chart 7 we included a short series of benzylidenemalononitriles as well as a-nitrostilbenes.116 Note that the most common functionalities associated with the chemistry of the nucleophilic addition to the C=C bond, namely aldehydes, ketones, esters, anhydrides and nitriles, are EW substituents present in dienophiles and dipolarophiles used in NED DA and 1,3 dipolar cycloadditions, and they are included in Table l.121 In Table 14, we summarize the global properties and local electrophilicity values for the series of benzylidenemalononitriles and a-nitrostilbenes. Both series present ethylene derivatives with large electrophilicity values, to > 2.3 eV, they being classified as strong electrophiles within the theoretical electrophilicity scale.39... [Pg.178]

Unhindered acrylic compounds afford high yields of Baylis-Hillman adducts at ambient pressure whereas substituted acrylic nitriles and esters require high pressure to lead to functionalized ethylenic derivatives in fair to excellent yields (Table 10.14). [Pg.321]

The polymerization of ethylene derivatives has recently become extremely important for the manufacture of plastics. Certain substituents in ethylene — those that increase the polarization — increase both the extent and the rate of polymerization. Such substituents are aromatic groups (as in styrene), oxygen-containing groups (as in acrolein, acrylic esters, and vinyl esters and ethers), and halogens (as in vinyl chloride). Multiplication of these substituents, however, depresses or completely suppresses the tendency to polymerize for instance, stilbene gives only a dimer when illuminated in benzene.14... [Pg.848]
