Spirophosphazenes and the parent triazaphosphole : differences and similarity in chemical reactivity
摘要:
The first step of hydrolysis of compounds 1,2 and 4 involves the protonation of the P = N nitrogen atom. 3 does not react with water in the absence of a catalyst. Protonation of compounds 1-3 by a strong acid such as CF3SO3H is studied by N-15 and P-31 nmr spectroscopy. In all cases the P = N nitrogen appears to be the strongest basic site.
