invariant manifold and another attractor not in the invariantmanifold. It is found that the boundary separating these basins has an interesting structure: The basin of the attractor not in the invariantmanifold is characterized by thin cusp shaped regions ("stalactites") extending down to touch the nonattracting chaotic set in the invariantmanifold. We also develop theoretical scalings applicable to

regioselective iodination of N-phenylureas was developed using iodine/trichloroisocyanuric acid in acetonitrile at room temperature. This protocol proved to be effective on a broad range of substituted N-phenylureas, forming the p-iodinated compounds in 65–96% yield under mild and neutral conditions. An efficient regioselective iodination of N-phenylureas was developed using iodine/trichloroisocyanuric
