Аннотация:Solid-state reactions of Cr, Mo, W, and Mn carbonyls with 3,6-di-tert-butyl-o-benzoquinone (Q) proceeding in molded powder-like mixtures (carbonyI--Q) treated with pulsesof elastic waves were studied. The products of the reactions of Q with Cr(CO)6, Mo(CO)6,and W(CO) 6 are paramagnetic semiquinone complexes of Cr, Mo, and W. The formation oftwo semiquinone complexes with one or two manganese atoms was detected in the reactionof Mn2(CO)I0 with Q.
