suffices to effect this reaction. In the absence of added MeCN, the protonation of the dimethyl cation leads to the ether complex mer-IrMe(Et2O)(MeCN) P32+, which is subsequently scavenged by adventitious water to yield mer-IrMe(H2O)MeCN)P32+. The crystal structure of this aquo complex, as its BF4 salt, shows a chain of BF4− /IrMe(H2O)(MeCN)P32+ units held together by two hydrogen bonds to each water molecule
在MeCN存在下,HBF 4 ·OEt 2与IrH 2(MeCN)P 3 +(1)(P = PMe 2 Ph)反应可快速转化为顺式,mer -IrH(MeCN)2 P 3 2+和H 2。与顺式,mer -IrMe 2(MeCN)P 3 +的相应反应要慢得多,但得到的顺式,mer -IrMe(MeCN)2 P 3 2+的相应产物。在不存在添加的MeCN,HBF的4 ·OET 2个变换的二氢化阳离子1至等摩尔的顺式,聚体-IrH(MeCN中)2 P 3 2+和IRH 4 P 3 + ; 0.5摩尔的酸足以完成该反应。在不添加MeCN的情况下,二甲基阳离子的质子化反应生成醚配合物mer -IrMe(Et 2 O)(MeCN)P 3 2+,随后用不定
水将其清除,得到mer -IrMe(H 2 O) )MeCN)P 3 2+。这种
