General Description

1,3,2-Dioxaphosphorinane, 5-butyl-5-ethyl-2-[2,4,6-tris(1,1-dimethylethyl)phenoxy]- is a complex chemical compound that consists of a dioxaphosphorinane ring attached to a butyl-ethyl group and a phenoxy group. The dioxaphosphorinane ring contains three oxygen atoms and one phosphorous atom, giving it unique chemical properties. The butyl-ethyl group adds alkyl chains to the molecule, while the phenoxy group, with its bulky, tert-butyl substituents, adds steric hindrance to the molecule. This chemical may have uses in various industrial and research applications, including as a potential pharmaceutical or agricultural compound. However, its exact properties and potential applications would need to be further investigated and studied.

Process for the preparation of acid esters

The present invention is directed to a process for the preparation of sterically hindered acid esters, e.g., organic phosphites, comprising contacting a sterically hindered hydroxyl-containing compound with an acid halide in the presence of an acid acceptor selected from the group consisting of: 1,5-diazabicyclo[4.3.0]non-5-ene (DBN), 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), 4-(dimethylamino)pyridine (DMAP), 1,4-diazabicyclo[2.2.2]octane (DABCO), or mixtures thereof, wherein said an acid acceptor is present in an amount sufficient to drive the reaction to completion.
