    • For instance, the addition of PhSiH3 to styrene catalyzed by IndNi(PPh3)Cl in the absence of any activator/initiator gives yields of 7, 1-Me-Ind, 56, 1-SiMe3-Ind, and 82, 1,3, SiMe3) 2-Ind, see ref. 12, It is important to emphasize, however, that for reactions run in the presence of initiators/activators, the steric bulk has little or no favourable influence on the reactivities unless the Ind ligand is substituted at both 1- and 3-positions. For instance, the addition of PhSiH 3 to styrene catalyzed by the combination of (1-R-Ind)Ni(PPh 3)Cl and NaBPh4 is no more effective with R, i-Pr (61, than Me (69, see ref. 7, This can be understood by recalling that the complexes (1-R-Ind)Ni(PPh3)X always adopt a configuration that places the PPh3 ligand away from the more bulky Ind substituent to avoid steric congestion see ref. 1, hence, placing a substituent at the 1-position has no advantage for
    • 3 ligand away from the more bulky Ind substituent to avoid steric congestion (see ref. 1); hence, placing a substituent at the 1-position has no advantage for increasing the lability of the phosphine ligand or the catalytic activities.
