The exchange of organyl groups between various diorganozinc compounds, R21Zn (R1 = CHMe2 (1), CH2(CH2)2Me (2), CH2C(Me)CH2 (3), CH2CHCHMe (4)) and R22Zn (R2 = Et (5), CH(Me)Et (6), CH2(CH2)3Me (7), CMe3 (8), Menthyl (9), Ph (10), Cyclohexyl (11)), has been followed by mass spectroscopy: molecular ions for the mixed compounds R1R2Zn were observed. The exchange equilibrium constants for 1–5 and 7–11
的有机基团的各种化合物diorganozinc之间的交换中,R 2 1的Zn(R 1 = CHME 2(1),CH 2(CH 2)2我(2),CH 2 C(Me)的CH 2(3),CH 2 CHCHMe(4))和R 2 2的Zn(R 2 =的Et(5),CH(Me)中的Et(6),CH 2(CH 2)3我(7),CME 3(8),薄荷(9),Ph(10),环己基(11))之后进行了质谱分析:观察到混合化合物R 1 R 2 Zn的分子离子。量热显示甲苯中1 – 5和7 – 11的交换平衡常数在10 8和0.2之间。相反,汇率是可比的。
