Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A process for preparing ##SPC13## which comprises reacting ##SPC14## wherein at least one of the group a, b, c, d and e is α-haloalkyl and a, b, c, d and e are independently selected from the group consisting of hydrogen, hydrocarbyl, alkyl, α-haloalkyl, halogen and nitro; R is selected from the group consisting of hydrogen, alkyl and aryl; R' and R" are independently selected from the group consisting of hydrogen and alkyl, and X is selected from the group consisting of bromine, chlorine and fluorine; the alkyl, hydrocarbyl and α-haloalkyl groups being from one to thirty carbon atoms, and aryl is selected from the group phenyl and napthyl, with 0.1 to 100 times the stoichiometric proportion of GOH wherein G is alkyl of 1 to 6 carbon atoms at a temperature from ambient to reflux.
Claim 2
Dependent Claim
135 words
A process for preparing ##SPC13## which comprises reacting ##SPC14## wherein at least one of the group a, b, c, d and e is α-haloalkyl and a, b, c, d and e are independently selected from the group consisting of hydrogen, hydrocarbyl, alkyl, α-haloalkyl, halogen and nitro; R is selected from the group consisting of hydrogen, alkyl and aryl; R' and R" are independently selected from the group consisting of hydrogen and alkyl, and X is selected from the group consisting of bromine, chlorine and fluorine; the alkyl, hydrocarbyl and α-haloalkyl groups being from one to thirty carbon atoms, and aryl is selected from the group phenyl and napthyl, with 0.1 to 100 times the stoichiometric proportion of GOH wherein G is alkyl of 1 to 6 carbon atoms at a temperature from ambient to reflux.
Claim 3
Dependent Claim
22 words
A process in accordance with claim 1 wherein ##SPC15## and R' and R" are alkyl groups of 1 to 6 carbon atoms.
Claim 4
Dependent Claim
51 words
A process according to claim 1 which comprises reacting ##SPC16## with methanol, wherein at least one of a, b and e is α-haloalkyl and a, b and e are independently selected from the group consisting of hydrogen, alkyl and α-haloalkyl, the alkyl and α-haloalkyl being from 1 to thirty carbon atoms.
Claim 5
Dependent Claim
19 words

Claim 6
Dependent Claim
21 words
The process of claim 4 wherein the solvent is selected from the group consisting of acetonitrile, benzene, toluene, cyclohexane and propionitrile.
Claim 7
Dependent Claim
10 words
The process of claim 4 wherein the solvent is acetonitrile.
Claim 8
Dependent Claim
26 words
The process of claim 1 wherein R' and R" are independently selected from the group consisting of hydrogen and alkyl of 1 to 12 carbon atoms.
Claim 9
Dependent Claim
18 words
The process of claim 1 wherein the hydrocarbyl and α-haloalkyl groups are from 1 to 12 carbon atoms.
Claim 10
Dependent Claim
18 words
