Popis: | The reaction of tetramethylsilane and sodium hydride in a mixed solvent of THF and HMPA (2:1 by volume), at reflux for 40 h, followed by the addition of PCl 3 yielded (Me 3 Si) 3 ( 1 ) in excellent yield by a simple, non-hazardous and facile route. This phosphine was readily converted into the known phosphide (Me 3 Si) 2 PH ( 2 ) by controlled hydrolysis. Reaction of this ligand with barium granules in a mixed liquid ammonia-THF solvent system at −40°C yielded the first barium silylphosphide, [Ba(P{SiMe 3 } 2 ) 2 (THF) 2 ] n ( 3 , which was characterized by IR, 1 H, 13 C and 29 Si NMR spectroscopy. |
