The synthesis and properties of 23 tris(dialkylamino)cyclopropenium (TDAC) cations with the bistriflamide anion, NTf2−, are described. D3h- and C3h-symmetric cations ([C3(NR2)3]NTf2 (R = Me, Et, Pr, Bu, Pent, Hex, Dec) and [C3(NRMe)3]NTf2 (R = Et, Bu, St), respectively) were synthesised by reaction of C3Cl5H with the corresponding amine. Reaction of alkoxydiaminocyclopropenium salts ([C3(NMe2)2(OMe)]+
合成和23三(二烷基氨基)cyclopropenium(TDAC)与bistriflamide阴离子的阳离子的性质,NTF 2 - ,中有描述。D 3h和C 3h对称阳离子([C 3(NR 2)3 ] NTf 2(R = Me,Et,Pr,Bu,Pent,Hex,Dec)和[C 3(NRMe)3 ] NTf 2( R = Et,Bu,St)分别通过C 3 Cl 5 H与相应的胺反应合成。烷氧基二氨基环丙烯盐([C 3(NMe 2)2(OMe)] +和[C 3(NEt 2)2(OMe)] +)与胺反应生成两个系列的C 2v不对称盐([C 3(NMe 2)2(NR 2)] NTf 2(R = Et,Pr, Bu,Hex)和[C 3(NEt 2)2(NR 2)] NTf 2(分别为R = Me,Bu,Hex))和两个系列的C s-对称盐([C 3(NMe 2)2(NRMe)] NTf 2(R =
