| Research Abstract |
A series of alkali (RCEE'M, E, E'=O, S, Se, Te ; M=Li, Na, K, Rb, Cs] and alkali earth metal salts [(RCEE')_2M, M=Ca, Sr, Ba] of thio- (RCOSH), seleno- (RCOSeH), telluro- (RCOTeH), dithio- (RCSSH) and selenothio- (RCSSeH) were synthesized. The reactions of these alkali metal chalcogenocarboxylates (1) with a variety of Group 13, 14, 15, 16 and 17 elemet halides were inevestigated. In addition, the reaction of 1 with transition metal halides were investogated. These reactions readily proceed at 0℃ to room temperature to give the corresponding main group element derivarives in good yields. The obtained compounds all are new compounds. The X-ray structural analyses of over 170 chalcogenocarboxylic acid derivatives have beenrevealed.
Film photo-sensitivity of these chalcogenocarboxylic acid derivatives was examined. Also, these compounds, particularlly selenno- and telluro-carboxylic acid derivatives were found to be very effective as photo-sensitizer. However, the later tellurium compounds are extremely labile toward oxygen and the development of more stable tellurium comounds toward oxygen which have activity as photo-sensitizer were desired.
The development of new convenient method evaluating film-photosensitivity are in progress.
