Abstract:
The Lewis acid B(C 6 F 5 ) 3 and the cyclic silane (Ar N 2 Si) 3 ( 1 ) (Ar N = o ‐(CH 3 ) 2 NCH 2 C 6 H 4 ) are useful precursors to access the silylene(II)–borane adduct Ar N 2 Si‐B(C 6 F 5 ) 3 ( 2 ). Treatment of 2 with water led to coordination and gave the Lewis pair (Ar N 2 H 2 O)Si‐B(C 6 F 5 ) 3 ( 3 ) that exhibits a hydrogen‐bond‐stabilized silanol unit. It can be converted into the siloxane [(HAr N ) 2 SiOB(C 6 F 5 ) 3 ] 2 O ( 6 ) by dehydrogenation in the presence of a base. Heteronuclear NMR spectroscopic data to characterize the compounds were supported by quantum‐chemical calculations.
