C4/C6–H double alkylations of indoles accomplished by arene-ligand-free ruthenium(II)-carboxylate catalysis. Base-assisted C2–H ruthenation enabled the C4/C6–H dialkylations with ample substrate scope. The robust C4/C6–H alkylations were demonstrated by gram-scale syntheses and late-stage diversifications. Mechanistic studies unraveled the unique features of ruthenium(II)-catalyzed C4/C6–H indole functionalizations

High-chi diblock copolymers are disclosed whose self-assembly properties are suitable for forming hole and bar openings for conductive interconnects in a multi-layered structure. The hole and bar openings have reduced critical dimension, improved uniformity, and improved placement error compared to the industry standard poly(styrene)-b-poly(methyl methacrylate) block copolymer (PS-b-PMMA). The BCPs comprise a poly(styrene) block, which can optionally include repeat units derived from trimethylsilyl styrene, and a second block that can be a polycarbonate block or a polyester block. Block copolymers comprising a fluorinated linking group L′ comprising 1-25 fluorines between the blocks can provide further improvement in uniformity of the openings.
