R2Si=P-SiR2F: 1,3-Sigmatropic migration of fluorine in a 2-phospha-1,3-disilaallyl derivative capable of conjugation and its conversion to phosphadisilacyclopropanes

More electronically diverse than the behavior of allyl is that of the 2-phospha-1,2-disilaallyl fragment. This was confirmed by the [1,3]-sigmatropic shift of fluorine in the title compound 1, which occurred rapidly at temperatures above 40°C. Ab initio c
