In the present work, we examine the soliton excitations in the relativ.s.ic Toda lattice model using the rotational expansion method, where the coupling between the lattice sites is varied. For specific choices of the coupling strength we proceed to analyze the nonlinear wave excitations arising in the model which are found to be dark, singular and periodic solitary wave profiles. These solitary wave profiles are admitted to show possible modulation in its amplitude.

A variety of alkyl-arenes and cyclohexane were converted to the corresponding ketones with NaC10 as the oxidant in the presence of 1-glycyl-3-methyl imidazolium chloride--copper（II） complex. This method contains simplified product isolation and catalyst recycling, affording benzylic C-H oxidation of alkyl-arenes imparting high yield of ketones. Furthermore, complex could be reused seven times without a significant loss of its catalytic activity.
