factors to Charton values was also observed when just alkyl substituents were employed but was nonexistent when substituents with more electronic effects were incorporated. The rate data suggest that a significant redistribution of charge occurs in the transition state, with an overall decrease in positive charge. The linear free-energyrelationship derived from selectivity factors is best understood by

each precursor in the synthesis of indium phosphide (InP) quantum dots (QDs). This approach was allowed by the exploration of the synthesis and reactivity of a series of sterically encumbered triarylsilylphosphines substituted at the para position of the aryl group, P(Si(C6H4-X)3)3 (X = H, Me, CF3, or Cl), as a contrast to P(SiMe3)3, the P3– source commonly employed in such syntheses.
