✦ Synopsis

Synthesis of Spiro Compounds from 2,2‐Dichloro‐4,6‐bis(trifluoromethyl)‐1,3,5,2λ^5^‐triazaphosphorine

The bis(trichlorophosphoranylideneamino) compound 6, obtained from 2,2‐diamino‐4,6‐bis‐(trifluoromethyl)‐1,3,5,2λ^5^‐triazaphosphorine (4), reacts with heptamethyldisilazane to give the spiro[5.5] compound 7. The reaction of 5 with PCl~5~ yields the spiro[3.5] compound 8. From N,N′‐dimethylethylendiamine and 3 the heterocyclic spiro[4.5] system 9 can be synthesized.
