Phosphirane
WebMar 25, 2015 · Abstract. Phosphiranes, three-membered phosphorus-containing heterocycles, have been prepared via reaction of tertiary phosphines dilithium derivatives with carbon tetrachloride. The elaborated method can be applied for preparation of some phosphiranes which are not easily accessible. Download to read the full article text. WebThe chemistry of phosphiranes commenced in 1963 when the first derivatives, including the parent phosphirane, were described in two patents. [7,8] Important aspects of the rapidly developing synthesis of phosphiranes and, in particular, their diverse reactivity, have been reviewed. [9,10]
