A chair conformation with an axial orientation of the phosphoryl or thiophosphoryl group is preferable for 2-dimethylamino-2-oxo- and-2-thiono-1,3,2-oxathiaphosphorinanes. The cis isomer of 2-dimethylamino-2-oxo-4-methyl-1,3,2-oxathiaphosphorinane has a similar structure with an equatorial orientation of the 4-methyl group, while the corresponding sulfide is characterized by a trans configuration with a reoriented positioning of the substituents attached to the phosphorus atom.

The authors found out that the greater wax moth (Galleria mellonella) harmed bee colonies by destroying up to 30 percent of honey in a beehive. They studied the results of experiments on controlling its behavior using a developed automated microprocessor system that maintained optical radiation sources duration.(Research purpose) To develop light technologies using a microprocessor-based automated system that allows controlling Galleria mellonella behavior by realizing attractive optical radiation characteristics.(Materials and methods) Galleria mellonella behavior was controlled by an automated system that the authors worked out for maintaining the required duration of the experiment and optical radiation parameters. The ATmega328 microcontroller was chosen as the main element of the developed microprocessor automated system. The authors created a program for it using visual programming FLProg version 5.3.0.(Results and discussion) The authors found that, regardless of the experiment duration, Galleria mellonella butterflies prefered radiation with 400 nanometers wavelength.(Conclusions) The authors determined that radiation with 400 nanometers wavelength and 10 minutes duration was attractive. They showed the ability to control Galleria mellonella behavior, luring butterflies to a specific place in the beehive with comfortable spectrum parameters. An automated system for controlling the greater wax moth butterfly behavior was developed on ATmega328 microcontroller by implementing attractive optical radiation characteristics.ΠΠΎΠΊΠ°Π·Π°Π»ΠΈ, ΡΡΠΎ Π±ΠΎΠ»ΡΡΠ°Ρ Π²ΠΎΡΠΊΠΎΠ²Π°Ρ ΠΌΠΎΠ»Ρ (Galleria mellonella) Π½Π°Π½ΠΎΡΠΈΡ Π²ΡΠ΅Π΄ ΠΏΡΠ΅Π»ΠΈΠ½ΡΠΌ ΡΠ΅ΠΌΡΡΠΌ, ΡΠ½ΠΈΡΡΠΎΠΆΠ°Ρ Π΄ΠΎ 30 ΠΏΡΠΎΡΠ΅Π½ΡΠΎΠ² ΠΌΠ΅Π΄Π° Π² ΡΠ»ΡΠ΅.

Steric structure of heterocycles containing phosphorus - 51. Conformational heterogeneity of 4,5;7,8-dibenzo-2-thiono-1,3,2-dioxaphosphocenes
1H and31P dynamic NMR, vibrational spectroscopy, and consideration of dipole moments have shown that 2-chloro-2-thiono-4,5;7,8-dibenzo(4,4β²-dimethyl-6,6β²-di-tert-butyl)-1, 3,2-dioxaphosphocene and its 2-ethoxy derivative are conformationally heterogeneous. The former exists as a three-component equilibrium mixture, and the latter as a two-component equilibrium mixture. In the chlorothiophosphate the boat-chair conformation predominates, with equatorial location of thiophosphoryl; next in frequency is boat-chair with axial orientation of P=S, and third is the deformed boat form. In the ethyl thiophosphate the preponderant form is the deformed boat with thiophosphoryl in the equatorial position. Β© 1991 Plenum Publishing Corporation
