Films were cast from liquid crystalline solutions of cellulose in an ammonia (NH3)/ammonium thiocyanate (NH4SCN) solvent. Microscopic examination of the cellulose liquid crystalline solutions used for the film formation exhibited the so-called conjug

Solutions of cellulose in a mixture of 27:73 (w/w) of liquid ammonia and ammonium thiocyanate become liquid crystalline at room temperature above a certain critical concentration which depends on the degree of polymerization of the dissolved cellulos

When bis(trimethylsilyl)silylene, (Me 3 Si) 2 Si, is generated in the gas phase by flow pyrolysis of methoxytris(trimethylsilyl)silane, (Me 3 Si) 3 SiOMe, or chlorotris(trimethylsilyl)silane, (Me 3 Si) 3 SiCl, the dominant reaction is rearrangement,

It is now possible, however, to generate 1-silacyclopent-3-en-1-ylidene (1) directly, and it reacts with butadiene to form in high yield a product which we have also found from recoiling silicon atoms and from the cocondensation of silicon vapor with
