Abstract
Official abstract text for this publication.
Methods of preparing compounds according to Formula (I): and salts thereof as well as their corresponding phosphine intermediates are provided herein, wherein R 1 and R 2 are different and each of R 1 and R 2 is independently selected from an organic radical that branches at the alpha carbon and an organic radical that branches at the beta carbon, and each of X and Y is independently O or S, and wherein said compound is a liquid at room temperature.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a compound of Formula (I): and salts thereof, wherein: R 1 and R 2 are different and each of R 1 and R 2 is a hydrocarbyl group containing a total of from 5 to 16 carbon atoms, wherein said hydrocarbyl group is chosen from (i) —CH 2 —CHR 3 R 4 where R 3 is methyl or ethyl and R 4 is alkyl; or —CR 3 (CH 2 R 5 )R…
