Beiträge zur Chemie des Bors, XLVII. Zur Alkylierung von Tris(dimethylamino)‐boran

Abstract: Die Alkylierung von Tris(dimethy1amino)-boran durch Metallalkyle erfordert drastischere Bedingungen als die Alkylierung der Borhalogenide. Das Alkylierungspotential gegenuber B[N(CH3)2]3 steigt in der Reihe SnR4 < CdRz .= ZnR2 , -BR3 i AIR3 (R -= CH3, C2H5). Die Reaktionen fuhren uber RB[N(CH3)& zu R2BN(CH3)2; in den aus MR, und B[N(CH&]3 sich bildenden Gleichgewichtsgemischen ist RzBN(CH3)z das bevorzugte Reaktionsprodukt. Fur einige spezielle Falle werden die Gleichgewichtskonstanten fur 122' angegeben. Subs… Show more

“…The most interesting aspect of the structure is probably the Tl I -N bond distance which is some 7 pm longer than in the corresponding Tl(III) trisamide, Tl[N(SiMe 3 ) 2 ] 3 , 209 pm. 23 A similar difference has been found between metal to chlorine bond distances in the gaseous, monomeric mono-and trichlorides of the less heavy group 13 metals Al, Ga, and In. 24 Even larger differences have been observed between the Tl I -C distances in [TlC(SiMe 3 ) 3 ] 4 (237 pm) 25 or TlC 6 H 3 (C 6 H 2 i Pr 3 ) 2 (234 pm) 26 and the Tl-C distances in Tl(III) organyls; mean value 215 pm.…”
