The present disclosure relates to a composite film comprising at least one liquid crystalline polyester and a fiber fabric, for example presenting a thickness of less than 0.10 mm, as well as articles comprising such composite films, exhibiting low dielectric constant and dissipation factors and being suitable for mobile electronic device components, for example flexible printed circuit board (FPC).
Copper-Catalyzed Hydrosilylation with a Bowl-Shaped Phosphane Ligand: Preferential Reduction of a Bulky Ketone in the Presence of an Aldehyde
Hollywood bowl: A highly active copper catalyst with a bowl‐shaped phosphane (bsp) ligand was used in the hydrosilylation reaction of bulky ketones. The preferential reduction of a bulky ketone in the presence of an unprotected aldehyde is unprecedented.
