Vinyl Ether Reactivity

Vinyl ether monomers vinyl ethers are known for more than 100 years.

Vinyl ether reactivity.

Vinyl ethers are well established as radiation curable materials exhibiting a wide diversity of chemistry 1. 2 modification of ethers. The complex between diethyl ether and boron trifluoride is an example. In other reactions which typically involve the breaking of the carbon oxygen bond ethers are relatively inert.

Vinyl methyl ether reacts vigorously with oxidizing materials. It is prone to polymerization leading to formation of polyvinyl ethers. It has been shown that both 2 vinyloxyethanol and the ethyl 2 hydroxyethyl acetal are extremely readily converted into the. In fact the reactivity of the vinyl group with tetrazines has been detailed in organic synthesis 11 and such a reactive pair was very recently employed to visualize and detect rna under bioorthogonal conditions.

Ethyl vinyl ether is made by reaction of acetylene and ethanol in presence of a base. It is miscible with alcohol acetone chloroform and ether and must be protected from light hawley. 2 2 allyl ether substrates. 12 we first used commercial phenyl vinyl ether 1 a as a model compound and tetrazine 2 a to challenge our decaging hypothesis.

Polymerization is typically initiated with lewis acids such as boron trifluoride. 2 1 vinyl ether substrates. A study has been made of the reactions of 2 vinyloxyethanol 1 2 divinyloxyethane ethyl vinyl ether and acetaldehyde ethyl 2 hydroxyethyl acetal with ethylene glycol and with diethylene glycol when heated and also in presence of catalysts concontrated hcl. The industrial production of vinyl ether monomers started in the 1930s based on the reppe reaction of acetylene with alcohols.

The vinyl carbonate 13 152 gives only copolymerization the ketene acetal 11 153 and the methyl vinyl ether 14 152 give both copolymerization and chain transfer in styrene polymerization whereas with the benzyl vinyl ethers 12 153 15 8 and 16 18 151 chain transfer is the only reaction detected. This review presents the scope and limitations of these methods according to reaction type specifically via ether modifications elimination reactions carbonyl olefinations alcohol additions and carbon oxygen coupling reactions. This mode of reactivity is analogous to the way vinyl acetate and vinyl chloride can be polymerized to form polyvinyl acetate and polyvinyl chloride respectively. A good selection of reactive monomers and prepolymers is commercially available.

Explosive in the form of vapor when exposed to heat flame or strong oxidizing agents. The alkene portion of the molecule is reactive in many ways. Reacts possibly explosively with halogens bromine chlorine or hydrogen halides hydrogen bromide hydrogen chloride baker 1980 p. These materials possess several attractive features such as low toxicity and high reactivity.

Ethers may react violently with strong oxidizing agents.
