The observed tendencies for the Bu3Al <— ER 3 adducts clearly reflect the influence of repulsive steric interactions between the large t-Bu and z-Pr substituents which become less important with increasing atomic radius of the central pentele. Such interactions overcompensate attractive dipolar... [Pg.238]

The most striking structural difference between analogously substituted, base-stabilized monomeric alanes is reflected by the degree of pyramidaliza-tion of the group 15 element. The sum of the bond angles of the pentele center (sum of the Si-E-Si and Si-E-Al bond angles) of the Me-substituted... [Pg.279]
