Claims
- 1. A process for the preparation of 2-substituted alkyl (2-substituted alkyl)-carbamates corresponding to the formula: ##STR10## wherein X and Y are halo, providing that if X and Y are not the same halo the V is the more electronegative halo,
- R, R.sub.1 and R.sub.2 are independently hydrogen or C.sub.1--10 alkyl or alkoxyalkyl; and
- R.sub.3 and R.sub.4 are independently hydrogen or C.sub.1--4 alkyl or haloalkyl and together may form a C.sub.3--4 alkylene group, comprising contacting an oxazolidone corresponding to the formula: ##STR11## wherein R, R.sub.1 and R.sub.2 are as previously defined, with an olefin corresponding to the formula:
- R.sub.3 HC.dbd.CHR.sub.4
- where R.sub.3 and R.sub.4 are as previously defined and an electrophile XY where X and Y are as previously defined at a temperature from about 25.degree. C. to about 100.degree. C.
- 2. A process according to claim 1 wherein R.sub.1 and R.sub.2 are hydrogen.
- 3. A process according to claim 2 wherein the oxazolidone is 2-oxazolidone, N-methyl-2-oxazolidone, N-ethyl-2-oxazolidone or N-methoxyethyl-2-oxazolidone.
- 4. A process according to claim 1 wherein the olefin is ethylene, propylene, allyl chloride, allyl bromide or cyclohexene.
- 5. A process according to claim 1 wherein the electrophile is chlorine or bromine.
- 6. A process according to claim 1 wherein less than equal molar amounts of olefin and electrophile based on the amount of oxazolidone reactant are contacted with the oxazolidone reactant.
