A medical lighting system is provided using electrodeless metal halide lamps and fiber optic light pipes to provide illumination to a plurality of medical appliances from a remote light source. Described herein are methods to make organoaminosilane compounds, or other compounds such as organoaminodisilanes and organoaminocarbosilanes, via the catalytic hydrosilylation of an imine by a silicon source comprising a hydridosilane. Differential rotation of the inner element with respect to the tubular element causes the articulable distal assembly to selectively assume the open and closed configurations.
