Preparation of Tris(trimethylsilyl)- and Tris(trimethylstannyl)amines

1,2,4‐Diazaphospholide Complexes of Tin(II): From Nitride Stannylene to Stannylenated Ammonium Ions

“…[1][2][3][4] The ready cleavage of Sn À N bonds makes this an attractive method for the synthesis of related stannylenes, probably because of the greatly enhanced reactivity of the Sn À N bond when compared with the Si À N bond. [5] Although tris(triorganostannyl)amine NA C H T U N G T R E N N U N G (SnR 3 ) 3 (R = organic ligand) [6] has been used as the N ligand or nitrogen source for the preparation of many metal complexes [7] and recently as a Lewis base for the synthesis of metal-coordinate onium ions [8] EA C H T U N G T R E N N U N G (SnMe 3 ) 4 + (E = N, [8d] P [8f] ), tris(organostannylenyl)-A C H T U N G T R E N N U N G amine NA C H T U N G T R E N N U N G (SnR) 3 has not yet been reported, presumably due to the highly reactive tin(II) species. Herein, we present the synthesis and crystal structures of a nitride tetrastannylene and a stannylenated ammonium ion stabilized by a samarium tetradiazaphospholido counterion that incorporates the 1,2,4-diazaphospholide ligand.…”

Reductive Electrochemical Silylation of Unsaturated Nitrogen Functionalities: A Simple and Efficient Synthesis of Precursors of Bis(trimethylsilyl)methylamine

“…This compound was identified by comparison with a sample synthetized according to a reported procedure. 20 Other Cyanides. Under the same conditions, other silyl cyanides led to the formation of the 2 + 3 mixture in the yields and proportions given in Table 2 (entries 1 and 2).…”
