Matrix isolation study of the thermal and photochemical reaction of OVCl3 and CrCl2O2 with cycloalkylamines

Matrix Isolation and Theoretical Study of the Reaction of Substituted Phosphines with CrCl2O2

“…Two of the product bands for this system were observed at 449 and 1011 cm -1 , very near known bands of Cl 2 CrO. This species has been observed by several research groups, ,− and has characteristic absorptions near 1014 and 450 cm -1 , with the exact position of these absorptions varying slightly from system to system, due to complexation of Cl 2 CrO to the oxidized product. The two product bands observed here (and their counterparts in the photochemical reactions described below for the other systems in this study) are very reasonably assigned to Cl 2 CrO.…”

Matrix isolation and theoretical investigation of the photochemical reaction of CrCl2O2 with benzenes substituted with electron withdrawing groups

“…Past studies in this laboratory have examined the matrixisolated products of the thermal and photochemical reactions of CrCl 2 O 2 , OVCl 3 , and OVF 3 with organic and inorganic substrates [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Specifically, two recent studies in this lab [33,34] examined the reactions of CrCl 2 O 2 with benzene and with methyl-substituted benzenes.…”

Matrix Isolation Investigation of the Photochemical Reaction of Benzene with CrCl2O2 and OVCl3

“…The matrix isolation technique was developed to facilitate the isolation and spectroscopic characterization of reactive intermediates − and may provide access to the study of initial intermediates in the above reactions. Past studies in this laboratory have examined the matrix-isolated products of the thermal and photochemical reactions of CrCl 2 O 2 and OVCl 3 with smaller organic and inorganic substrates. ,− Also, Parker and Davis have studied the reaction of oxygen atoms (photochemically generated from ozone) and benzene using matrix isolation and have shown that an oxygen atom addition to benzene leads first to the formation of 2,4-cyclohexadienone, which then photolyzes to butadienylketene (hexa-1,3,5-triene-1-one). These results help guide the present study, which focused on the utilization of matrix isolation to identify intermediates in the reactions of CrCl 2 O 2 and OVCl 3 with C 6 H 6 .…”
