Reactions d'Heterocycles Oxygenes avec Les Trialcoylsilyl-, Germyl- et Stannylphosphines: I: Dialcoylphosphinoalcoxy-Germanes, -Silanes et -Stannanes

摘要

The reactions of trialkylmetalphosphines R3MPR'2(M = Si, Ge, Sn) with the cyclic ethers lead, by cleavage and insertion on the metal-phosphorus bond, to dialkylphosphinoalcoxysilanes, germanes and stannanes. The silylphosphines are more reactive than isolog germyl- and stannylphosphines in this type of reaction, and only silylphosphines cleave the tetrahydrofuran
