The study presents the synthesis and characterization of a novel monospirocyclic phosphazene derivative, 4',4',6',6'-tetrachloro-3-(2-methoxyethyl)-3H,4H-spiro-1,3,2-benzoxaza phosphinine-2,2'-[1,3,5,2,4,6]triazatriphosphinine (SP1). The compound was synthesized by reacting hexachlorocyclotriphosphazene (N3P3Cl6) with the N/O donor-type molecule 2-{[(2-methoxyethyl)amino]methyl}phenol. The synthesized SP1 was characterized using various analytical techniques, including elemental analyses, mass spectrometry (MS), Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR) spectroscopy, and single-crystal X-ray diffraction analysis. The purpose of these chemicals and techniques was to verify the structure and investigate the properties of the newly synthesized compound. The study also employed density functional theory (DFT) calculations using the B3LYP method with a 6-311++G(d,p) basis set to predict the electrophilic and nucleophilic attack centers in SP1, further understanding its reactivity and potential applications in areas such as biomaterials, protective coatings, drug delivery, and fire-resistant materials.
