Electronically Tunable Compact Trialkylphosphines:SMAPs-bridged Bicyclic Phosphines

摘要

A series of silicon-constrained monodentate trialkylphos-phines SMAPs bearing a Si substituent with diverse electronic natures were synthesized.DFT calculations and NMR measurements indicated that these compounds constitute a class of electronically tunable trialkylphosphines.The tunable range of donor power overlaps those of tri(tert-butyl)phosphine and monoalkyldiarylphosphines.
