The phosphane unit is deprotonated in the reaction of dialkylzinc with H 2 PSi t Bu 3 and (thf) 2 Ba[N(SiMe 3 ) 2 ] 2 to give the title compound (molecular structure shown), which has a coordinatively unsaturated barium center. In the absence of excess THF, the zinc‐bound alkyl groups are activated by formation of Ba‐C Et ‐Zn three‐center bonds.
