The reactions of boron trifluoride with the organostannylene RSnCl {R = 4‐ t Bu‐2,6‐[P(O)(O i Pr) 2 ] 2 C 6 H 2 } and the organosilane RSiMe 3 provided the corresponding 1:1 and 1:2 complexes, respectively, through the formation of P=O→B interactions. In the former reaction, even with excess BF 3 · OEt 2 , no Sn→B complexation involving the lone electron pair at the tin(II) center was observed. The experimental results are supported by DFT calculations.
