heating to give the chromium(IV) dimer [Cr(µ-NC6H2Me3-2,4,6)(NC6H2Me3–2,4,6)(PMe3)]2. The interaction of CrCl2(NC6H2Me3-2,4,6)2 with the Grignard reagent derived from 4-tert-butylbenzyl chloride gave not a dialkyl but an amidochromium(IV) dimer CrCl(µ-NC6H2Me3–2,4,6)[N(CH2C6H4But-4)(C6H2Me3-2,4,6)]}2, while on interaction with MgEtBr in the presence of PMe3 it gave the dichromium(V) compound (2,4,6-Me3H
铬(VI)的第一芳基化合物CrCl 2(NR)2(R = 2,4,6-Me 3 H 2 C 6或2,6-Me 2 H 3 C 6)是通过与CrCl 2(NBu t)2与芳基异氰酸酯。与2,6-Pr i 2 C 6 H 3 NCO的相似相互作用得到二聚体铬(V)化合物[CrCl(µ-NBu t)(NC 6 H 3 Pr i 2 -2,6)] 2。氯化物CrCl 2(NC 6 H 2 Me 3 -2,4,6)2与路易斯碱形成加合物,例如CrCl 2(NC 6 H 2 Me 3 -2,4,6 )2(PMe 3)2和[用AgBF 4获得了Cr(NC 6 H 2 Me 3 -2,4,6)2(叔)] [BF 4 ] 2(叔= 2,2':6',2''-吡啶)。NaR'(R'= OSiMe 3,OC 6 H2 Me 3 -2,4,6,SC 6 H 2 Me 3 -2,4,6,SC 6 F 5或SC 6 H
