Abstract: The invention provides users the ability to attach a battery charger intended to recharge the battery of an electronic device to a key ring, key set, or any of the like. The shell of the electronic device battery charging device includes an extruding hole which allows for an attaching device such as key ring, clip, or fastener to be connected to its body. The cord in which transfers the electricity from the power source into the device, has the capabilities to be refracted into the shell of the battery charging device which allows for storing and/or travel of the invention, without the inventions' cord to remain uncoiled.

Abstract: A process for manufacturing (R)-propynylaminoindans, and alternatively, a process for manufacturing (S)-propynylaminoindans. The chiral propynylaminoindans include alkoxy or alkylcarbamates derivatives. The process comprises transfer or pressure hydrogenation in the presence of an optically active catalyst to reduce 1-indanones. The chiral product, either (S)- or (R)-indanols undergo nucleophilic substitution to produce the named product. In an additional aspect, the invention relates to novel intermediates and compounds, namely, substituted indanones, substituted (S)-indanols and substituted (R)-indanols.
