IPC: C07D277/32
Abstract: 546,994. Thiazole compounds. BOON, W. R., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 4, 1940, No. 17239. [Class 2 (iii)] Thiazole-2-carboxylic acid esters, substituted in the 4-position and optionally also in the 5- position by alkyl or substituted alkyl groups, are prepared by condensing alkyl thio-oxamates with α-halogeno-ketones. On hydrolysis, the acid is first formed and then the carboxylic acid group is eliminated, in many cases simultaneously and in others upon gentle heating, with formation of the corresponding thiazole. As suitable ketones are mentioned chloracetone, ethyl α-bromethyl ketone, 3-chloro- and bromo- 5-hydroxypentan-2-one (see Specification 472,396) and esters thereof such as 3-aceto-3- chloropropyl-(1) acetate; whilst methyl, ethyl and isobutyl thio-oxamates are referred to. The condensation preferably takes place in a solvent and in presence of an acid-binding agent. The hydrolysis is conveniently effected with the aid of aqueous alkali and the decarboxylation by heating with a dilute mineral acid ; both processes take place simultaneously on heating with dilute mineral acid. Examples are given of (1) the interaction of ethyl monothio-oxamate with chloracetone to give ethyl 4-methylthiazole-2-carboxylate and its hydrolysis to 4-methylthiazole; (2) the condensation of ethyl monothio-oxamate with 3-brom-3- acetopropanol-1 and the hydrolysis of the resulting ethyl 4-methyl-5-#-hydroxyethylthiazole-2-carboxylate to give 4-methyl-5-#- hydroxyethylthiazole, which is an intermediate for the preparation of Vitamin B1; (3) the preparation of ethyl 4-methyl-5-#-acetoxyethylthiazole-2-carboxylate by interaction of ethyl monothio-oxamate with 3-chloro-3-acetopropyl acetate and its hydrolysis to 4-methyl-5-#- hydroxyethylthiazole. Specifications 472,396 and 472,459 are referred to.

[Also in Divisions H1 and H3] The threshold field at which Gunn Effect oscillations arise is controlled by means such as a source of radiation 78 or a field effect gate contact 110, Fig. 8A (not shown) which introduces extra charge carries into the semi-conductor. Such semi-conductor 12, e.g. Ga As or IP, may be so deficient in charge carries that only in the presence of the radiation (e.g. light) or a suitable potential on the gate electrode are sufficient carriers injected to enable the Gunn Effect to arise. It is also possible to employ both the field effect and radiation-operated mechanisms in conjunction, e.g. by using a field effect device structure in which the gate electrode contacts an insulating layer on the semi-conductor body, this layer being made transparent to the radiation.
