Boron Lewis Acid Catalyzed Hydrophosphorylation of N -Heteroaryl-Substituted Alkenes.

This article discusses the synthesis and characterization of various phosphonate compounds. The authors developed a method using a boron Lewis acid catalyst to add the P-H bond of alkenes with H-phosphonates, resulting in the formation of β-N-heteroaryl alkylphosphonates. The document provides detailed information on the preparation, purification, and physical properties of these compounds, as well as spectroscopic data such as NMR spectra and IR spectra. The compounds synthesized have potential applications in various fields. The authors are researchers in the field of organic chemistry with a focus on catalysis. [Extracted from the article]
