What is produced by the reaction of trimethyl phosphite with Chloroacetoacetate?
For example, trimethyl phosphite and methyl α-chloroacetoacetate yield the insecticide phosdrin usually as a 3:2 mixture of cis- and trans-isomers (Fig. 4.39.
Does phosphite exist?
Phosphite ( ; Phi), a reduced form of phosphate ( ; Pi), is widely marketed as either a fungicide or fertilizer or sometimes as a biostimulant.
How do you remove triethyl phosphite from a reaction mixture?
[0048] A procedure for removal of the triethyl phosphite involves reducing the internal pressure of the vessel holding the reaction mixture and heating the vessel at a given temperature to distill off the triethyl phosphite, a low-boiling product, from the reaction system.

What formula is phosphite?
What elements make up phosphite?
In nature, P does not exist as a free element, but rather in combination with other elements, such as oxygen (O) or hydrogen (H). It occurs in a fully oxidized form (P has valence of +5) as phosphate anion ( ; Pi) and with one less oxygen (P has valence of +3) as phosphite ( ; Phi).

Does trimethyl phosphate cause aspermia?
Trimethyl phosphate primarily affected epididymal spermatozoa, probably by action of sperm motility. Trimethyl phosphate causes aspermia in D. melanogaster males. Evidence from cytological studies of larval testes suggests that the chemosterilizing effect of the chemical is upon early primary spermatocytes.
What can infrared and multinuclear magnetic resonance spectroscopy tell us about solute–solvent interactions?
Infrared and multinuclear magnetic resonance spectroscopy (NMR) studies of trimethyl phosphate in 24 different solvents were undertaken to investigate the solute–solvent interactions and to correlate solvent properties such as acceptor number and dielectric constant with the infrared band shift and the 13C and 31P NMR chemical shifts.
