Mercury compounds of the types HgR1R (R1 = C(SiMe3)3; R = Me, iPr, Bu, tBu or Ph) and HgR2R(R2 = C(SiMe2Ph)3; R = Me, Bu, CH2Ph or Ph) have been prepared. Those containing R1 were made by reactions of the bromides HgR1Br with the Grignard reagents MgRX, and those containing R2 by reaction of HgR2Cl with LiR or, for R = CH2Ph, with Mg(CH2Ph)Cl. Replacement of one R group in HgR2 by the bulky R1 or R2
HgR 1 R(R 1 = C(SiMe 3)3 ; R = Me,i Pr,Bu,t Bu或Ph)和HgR 2 R(R 2 = C(SiMe 2 Ph)3 ; R = Me,Bu,CH 2 Ph或Ph)已准备好。含R 1的化合物是通过
溴化物HgR 1 Br与
格氏试剂MgRX反应制得的,而含R 2的化合物是通过HgR 2 Cl与LiR的反应制得的,或者对于R = CH 2 Ph,是与Mg(CH 2 Ph)Cl合成的。。取代HgR 2中的一个R基团庞大的R 1或R 2基团导致的热稳定性大大提高,199 Hg共振明显移至较低频率,并且HgR键的偶联常数增加。化合物HgR 2 Cl在
四氢呋喃中不与LiR 2进一步反应,但与LiR 1给出HgR 1 R 2;SiMe 2 Ph基团在低温下在CH 2 Cl 2中的溶液中的排列似乎与固体中的排列不同。
