Claims18
A process for preparing a distribution of compounds of Formula (Ia) from a compound of Formula (III), the process comprising:
- (a) contacting the compound of Formula (III) with an alcohol, R3OH, to form a distribution of compounds of Formula (II);
- and
- (b) contacting the distribution of compounds of Formula (II) with an acyl halide or its acid analog, R4C(O)X, to form the distribution of compounds of Formula (Ia);
- wherein:
- R1, R3, and R4 independently are hydrocarbyl or substituted hydrocarbyl;
- X is a halide ion or a hydroxyl group;
- Z is sulfur, sulfoxide, or sulfone;
- k is an integer of 1 or greater;
- and
- n is an integer of 1 or greater.
