“…[ 24 , 25 , 26 , 27 , 28 ] To date, a row of different primary silylphosphanes and ‐arsanes are known,[ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ] whereas primary stibanes are hardly known so far and in some cases are also unstable at room temperature. [ 37 , 38 ] Bulky organic residues or further residues such as NacNac‐gallium‐based substituents (NacNac=diketiminate) are required to increase kinetic stability. [ 39 , 40 , 41 , 42 , 43 , 44 ] Primary silylstibanes, in contrast, are not known up to now.…”
