The 1:1 reaction of [(Me 3 Si) 3 SiLi·3THF] with (iPr 2 N)BCl 2 in hexane provides [{(Me 3 Si) 3 Si}·(iPr 2 N)BCl] ( 2 ) in good yield as a colorless crystalline solid. This compound combined in a 1:1 ratio with LiPPh 2 in DME gives [{(Me 3 Si) 3 Si}·(iPr 2 N)B(PPh 2 )] ( 3 ) as a yellow crystalline solid. The new compounds were characterized by IR, MS and 1 H, 13 C{ 1 H} and 11 B NMR spectroscopy and the molecular structure of 3 was determined by X‐ray structure analysis.
