Summary of "Barium siloxides and catalysed formation of Si-O-Si' motifs."

The first unsupported barium siloxide, the homoleptic dimer [Ba2{μ2-OSi(SiMe3)3}3{OSi(SiMe3)3}], is presented, and its structural features are discussed in the light of DFT computations. This complex, together with the related [Ba{μ2-OSi(SiMe3)3}{N(SiMe3)2}]2 and their parent [Ba{N(SiMe3)2}2]2, mediate the formation of asymmetric siloxanes R3Si-O-SiR'3 through the first case of main group metal-mediated dehydrocoupling of silanols and hydrosilanes. Early kinetic analysis highlights an unusual catalytic manifold.

Recent advances in the synthesis of axially chiral biaryls via transition metal-catalysed asymmetric C-H functionalization.

Axially chiral biaryl motifs are widely present in natural products and pharmaceuticals. Moreover, they have been broadly used as privileged ligands in asymmetric catalysis. Over the past few decades,...

A De Novo Shape Motif Discovery Algorithm Reveals Preferences of Transcription Factors for DNA Shape Beyond Sequence Motifs.

DNA shape adds specificity to sequence motifs but has not been explored systematically outside this context. We hypothesized that DNA-binding proteins (DBPs) preferentially occupy DNA with specific st...
