1- ethoxyethyl carbamate

In this reaction, carbamate esters were obtained after long reaction times (70 h), in 0.06-11% yield, depending on the olefin/amine molar ratio (l-10mol/mol) and temperature (308-353 K). Since 1-ethoxyethyl carbamate was formed as the sole regio-isomer product, but there was no formation of the 2-ethoxyethyl ester, the reaction was believed to proceed by an electrophilic addition to the vinyl ether of carbamic acid, formed by reversible reaction of C02 with amine (see Equation 6.1). [Pg.142]

The carbamates 327 (R R2 Pr or Bu) react with t-butylthiol, malonic acid and ethoxyethylene under irradiation to yield the (ethoxyethyl)amines 333 via the radical cations 332. The A-allyl analogues 334 (R = Pr or PhCH2) cyclize to pyrrolidines 335382. [Pg.600]

The transfer of a carbamate moiety to olefins has been documented only in very few cases, using activated unsaturated substrates. For example, Yoshida and Inoue reported the selective (100%) formation of 1-ethoxyethyl N,N-dialkylcarbamate esters by the reaction of C02 (5 MPa) with ethyl vinyl ether and secondary amines R2NH (R = Me, Et) in the absence of any catalyst (Equation 6.11) [85]. [Pg.142]
