ADDITION OF FLUOROACETYLENES TO GROUP V HYDRIDES

Abstract

Compounds of the type R2EH react readily with CF3C≡CCF3 to give R2ECH(CF3)=C(CF3)H (E = N,P, As), and with CF3C≡CH to give R2ECH=CHCF3(E = N, As) and R2EC(CF3)=CH2 (E = As). The isomer distribution of the products is obtained from their n.m.r. spectra and the mechanism of the addition reaction is discussed.
