A Practical, Two-Step Synthesis of 2-Substituted 1,3-Butadienes
A two-step procedure for preparing 2-alkyl-1,3-butadienes is described. Cuprate addition to commercially available 1,4-dibromo-2-butene yields 3-alkyl-4-bromo-1-butene, a product of SN2′ substitution.

Synthesis and characterization of 1-amino-4-methylthio-2-nitro-1,3-butadienes
Treatment of 3-nitrothiophene with prim. and sec. amines, followed by S-methylation leads to (Z,Z)-1- amino-4-methylthio-2-nitro-1,3-butadienes (3). Oxidation of these with LTA yields a mixture of the 2-methylthio-4-nitropyrroles (6) and the acetoxylated

Ruthenium-Catalyzed Silylation of 1,3-Butadienes with Vinylsilanes
A novel method for the synthesis of 1-silyl-substituted 1,3-butadienes, based on [RuHCl(CO)(PCy3)2]-catalyzed silylative coupling of terminal (E)-1,3-dienes with vinylsilanes, is reported. The reaction provides a facile and straightforward access to (E,

Zn/Al‐NO3 layered double hydroxide offers a low‐zinc alternative for sulfur vulcanization of nitrile rubber, reducing nominal zinc loading by an estimated 71%. Its potential as a vulcanization activator depends on the curing system: conventional curing preserves tensile strength despite slower kinetics, whereas efficient curing maintains comparable ...
