Abstract. The chemistry of sulfur-nitrogen compounds has several features of interest and importance: stability of the sulfur-nitrogen bond, tendency to form six- and eight-membered rings, ring contraction, polymerization, and negative ion formation. KEYWORDS (Audience):
Photochemical Study on the Reactivity of Tetrasulfur Tetranitride…
To elucidate the multifaceted but poorly understood chemistry of the pivotal polysulfur−nitrogen heterocycle, tetrasulfur tetranitride (S 4 N 4, 1), its photochemistry was studied in Ar matrices. Thereby two primary intermediates and a secondary one ( 2 − 4 ) were detected, and their UV−vis and IR spectra were identified through specific ...
