An extraordinary downfield ‐ shifted 29 Si{ 1 H} NMR signal is seen at δ =338.5 for the platinum silylene complex [(dippe)(H)Pt=SiMes 2 ][MeB(C 6 F 5 ) 3 ] ( 2 ). This remarkably stable metal silylene complex was obtained from 1 in the first intramolecular 1,2‐hydride migration from silicon to a transition metal. dippe= i Pr 2 PCH 2 CH 2 P i Pr 2 , Mes=2,4,6‐Me 3 C 6 H 2 .
