In this paper we have present the results of study for electronic influence of the metal fragment on the regioselectivity of addition of •CCl3 (R1 ) and •Bu t (R2 ) radicals to the complexes (η2-C60)IrH(CO)(PPh3)2 (I), (η2-C60)IrH(CO)[(+)DIOP] (II), (η2-C60)Os(CO)(PPh3)2(CNBut) (III) and on the stability of spin-adducts (SA). It was found that the addition of R1 and R2 to I-III unlike methano- or pyrrolidinofullerenes the ESR spectra exhibit signals from some regio-isomers which substantial different by the g-factor. The assignment of the individual signals to definite regio-isomers was made. The rate constants of the addition of radicals R1 and R2 to carbon atoms of individual bonds in I-III were determined using the method of competing reactions. |
