Abstract
Cp degrees(2)<(Zr(PMesP)over bar>Mes) (Cp degrees = eta(5)-C5Me4Et, Me s = 2,4,6-Me3C6H2) reacts with phenylacetylene with cleavage of the Zr -P bonds and formation of Mes(H)P-P(H)Mes (1). 1 is also obtained from LiPHMes and 1,2-dibromoethane. The P-31 NMR spectrum of 1 shows the p resence of both isomers d,l and meso form). A crystal structure determ ination carried out on meso-Mes(H)P-P(H)Mes showed that in the solid s tate the bulky Mes groups have a trams arrangement.
