Title: Improvements in the manufacture and production of nitrogenous condensation products
IPC: C07D217/14
Filed: 1934-01-16
Abstract: Nitrogenous condensation products are prepared by acting with condensing agents of the type of anhydrous aluminium chloride on dicarboxylic acid imides corresponding with the formula <FORM:0431790/IV/1> wherein A and B are aromatic radicles, B having at least one free o-position; of the free linkages attached to the carbon atoms at least two are satisfied by hydrogen, and the others may also be thus satisfied, or they may form part of an isocyclic ring system of which the two carbon atoms are members, or they may be satisfied by substituents which permit the formation of a double linkage under the reaction conditions.  A new ring-closure appears to take place with formation of isoquinolinecarboxylic acid derivatives. These may be treated with acid condensing agents to effect further ring-closure.  Starting materials comprise imides derived from phthalic acid and its halogen and alkyl derivatives, naphthalene o-or peri-dicarboxylic acids and b -phenylethylamine, b  - oxyphenylethylamine, b  - naphthylethylamine or o-aminodiphenyl.  In examples: (1) b -phenylethyl-phthalimide (from phthalic anhydride and b -phenylethylamine) is treated with sodium-aluminium chloride at 160 DEG  C. to give a  - phenylisoquinoline - o<1> - carboxylic acid; treatment of this with fuming sulphuric acid gives b z-3-azabenzanthrone; (2) an imide is formed from phthalic anhydride and o-aminodiphenyl and this is treated with sodium - aluminium chloride at 165 DEG  C. to give a -phenylphenanthridine - o<1> - carboxylic acid; treatment of this compound with chlorsulphonic acid gives b z1.2 - benzo - b z3 - azabenzanthrone; (3) an imide is formed from phthalic anhydride and b -(4-chloro-) phenylethylamine and treated with sodium-aluminium chloride at 180 DEG  C., to give 1-phenyl-7-chloroisoquinoline-2<1>-carboxylic acid; treatment of this compound with chlorosulphonic acid gives 4-chloro-b z-3-azabenzanthrone: (4) an imide is formed from 4-chlorophthalic anhydride and p-phenylethylamine and treated with sodium-aluminium chloride at 160 DEG  C., to give a chlorophenylisoquinoline carboxylic acid which on further treatment with fuming sulphuric acid gives a mixture of 6- and 7-chloro-b z-3-azabenzanthrone: (5) the imide from o.o<1>-diaminodiphenyl and phthalic anhydride is treated with aluminium chloride at 200 DEG  C., to give a product assigned the formula  <FORM:0431790/IV/2> Treatment of this product with sodium-aluminium chloride at 150 DEG  C. gives flavanthrone. Reference is made to the treatment of starting materials of the type:-- <FORM:0431790/IV/3> and <FORM:0431790/IV/4> and ferric, antimony, and zinc chlorides are also mentioned as agents of the aluminium chloride type.

[Class 40 (v)] A detection system for frequency or phasemodulated short waves, e.g. one centimetre in wave-length, comprises means such as a slotted metallic plate for setting up an interference pattern, the receiving aerial or aerials being situated at a suitable point in this pattern. As indicated in Fig. 1, a plate 1 with slots 2 will, for any particular frequency, set up an interference pattern with strong reception at points A, B, C and zero reception at D, E. One or more aerials, which may be dipoles 4, are set up at points where the reception is a maximum for waves of one extreme carrier frequency, the reception throughout the deviation range then being approximately a linear function of the instantaneous carrier frequency. The plate 1 may have a large number of slits as indicated in Fig. 2, and the detecting elements in the form of probes 9 are arranged in a suitable curve. The probes are insulated from a supporting sheet 7 and are all connected to a wire or strip 10 through phasing elements 11 which serve to bring the received currents into phase agreement in the conductor 12 leading to a crystal, bolometer, or like detector. Separate detectors may be employed for each aerial and the phasing arrangements omitted. Suitable positions for the receiving aerials may be found by propagating through the slits a local wave of a frequency equal to an extreme frequency of the signal carrier wave.
