The formation of substitution products of aldehyde fragments was observed during the interaction of substituted 2,5-diphenyl-1,3,2,5-dioxabor-... 

Interaction of substituted arenediazonium salts with potassium O. O-diphenylphosphorodithioates gave a series of solid diazonium salts which decomposed explosively when heated dry [10], The unique failure of diazotised anthranilic acid solutions to produce any explosive sulfide derivatives under a variety of conditions has been investigated and discussed [6]. Preparation of diaryl sulfides from interaction of diazonium and thiophenoxide salts led to violent explosions, attributed to presence of some arenediazo sulfide during subsequent distillation of the diaryl sulfides. Precautions are detailed [11]. A safe method of preparation of diaryl sulfides from diazonium tetralluoroborates and sodium benzenethiolate in DMF is now available [12],...

Among the reactions of the first type, the interactions of substituted 1,3-cyclohexanediones 103a-c with various UNs (82JOU544), including cya-nonitroalkenes 25c (84ZOR2481), are the most developed. Probably, due to... 

Interaction of substituted dienediamines with ethylenediamine yields im-idazo[3,2-n]pyridine derivatives (95JHC477). 3-Arylaminoindoles, with distinct enamine properties, are the starting materials for the synthesis of indolo[3,2-b]quinoline derivatives [96KFZ(7)42]. a-Carboline derivatives can be obtained from enamine-based 3-dimethylamino-2-indolinones [96KFZ(9)35, 96KFZ(10)32], The synthesis and transformation of enamines based on the pyrido[l,2-n]pyrazine ring system into imidazo[l,2-n]pyridine and imidazo[l,2-a]pyrimidine derivatives have been reported...

In another paper, Egorochkin and coworkers30 have reported Avch values for the interaction of substituted acetylenes with dimethylformamide and with tetrahydrofuran (sets CP5 and CP6 respectively, Table 5). Correlation of set CP5 with the LDRA equation... 

As mentioned above, there is a scarcity of data on how variations in ketone structure affect CT quenching rates. A comparison of the interactions of substituted benzenes with triplet acetophenone and triplet a-trifluoroacetophenone is interesting 182,182). The relative reactivities of various hydrocarbons towards triplet acetophenone are suggestive of direct hydrogen atom abstraction by the triplet ketone. The low reduction potential of the trifluroketone enhances the rate of CT quenching so much that photoreduction proceeds almost entirely by a... 

N and chemical shifts for quinoxaline and spectra of fluoroquinoxaiines have been reported. O NMR studies of electronic and steric interactions of substituted quinoxaline-2,3(l//,4//)-diones have also been reported. ...

Fietzek et al. studied various MPcs as sensitive coatings on QCM for the detection of a variety of VOCs [44]. They also used thickness shear mode resonators (TSMRs) to study the interaction of substituted phthalocyanines (PCs) with benzene, toluene.

In order to exclude the possibility that inhibition of phytoene desaturation is caused by indirect or regulatory mechanisms, direct interaction of substituted phenylthiazolines with phytoene desaturase was demonstrated by in vitro studies. As a result, with increasing concentrations, more phytoene is retained which means that less phytoene was desaturated. Therefore, less 3-carotene is formed as the end product of this in vitro biosynthetic chain. Interaction of phenylthiazolines is very similar to inhibition of this enzyme by flurtamone. For the latter herbicide, it has been shown to be a reversible non-competitive inhibitor of phytoene desaturase (P). 

Type A (S—C—N + C—C) Syntheses.—4-Hydroxy-A -thiazolines have been produced by Hantzsch s method. The synthesis of A -thiazolines by the interaction of substituted thioureas and diethyl acetylenedicarboxylate (see these Reports, Vol. 2, p. 617) has been applied to the production of 5-alkoxycarbonylmethylene-2-(2-pyridylamino)-A -thiazolin-4-ones (85)." ...
