Dyna mic ۱H NMR along Doub le Bond in the New with The oretical Study arou nd the C arbon-Ca rbon Stable P hosphoru s Ylide Derived fro m Hexam ethyl Phosphorous Triamid

Ylides usually exist as a mixture of the tw o geometrical isomers (Z and E). These comp ounds exhibit dynamic ۱H NMR effect [۱] that affo rds good informatio n regardingthe interc hangeable process of r otational iso mers that p rovide important kinetic data. We now describe theoretical studies [۲] as a co mplementar y investigation on the basis of rotation aroun d the carbon-carbon double bond in a phosphoru s ylide ۴a.
