DirectedtridentateLewisacidsbased on the 1,3,5‐trisilacyclohexane skeleton with three ethynyl groups [CH2Si(Me)(C2H)]3 were synthesised and functionalised by hydroboration with HB(C6F5)2, yielding the ethenylborane CH2Si(Me)[C2H2B(C6F5)2]}3, and by metalation with gallium and indium organyls affording CH2Si(Me)[C2M(R)2]}3 (M=Ga, In, R=Me, Et). In the synthesis of the backbone the influence of
