DOI: 10.1021/acs.jnatprod.8b01073
Abstract: Identified through a bioinformatics approach, a nonribosomal peptide synthetase gene cluster in Alcanivorax pacificus encodes the biosynthesis of the new siderophore pacifibactin. The structure of pacifibactin differs markedly from the bioinformatic prediction and contains four… read more here.

DOI: 10.1039/c6dt04608h
Abstract: Diethynyldiphenylsilane (1) and divinyldiphenylsilane (2) were functionalized by hydrosilylation reactions with HSiMe2Cl, HSiMeCl2 and HSiCl3. Fluorination of the resulting compounds generates bidentate open-chain Lewis acids of increasing acidity. All semi-flexible [Ph2Si(CH[double bond, length as m-dash]CHSiFnMe3-n)2… read more here.
