Diphenyl sulfide and its analogues can also be produced by coupling reactions using metal catalysts. [5] It can also be prepared by reduction of diphenyl sulfone. [6] Diphenyl sulfide is a product of the photodegradation of the fungicide edifenphos. [7] Diphenyl sulfide is a precursor to triaryl sulfonium salts, which are used as photoinitiators.
Multisystem inflammatory syndrome in children (MIS-C), or paediatric inflammatory multisystem syndrome (PIMS / PIMS-TS), or systemic inflammatory syndrome in COVID-19 (SISCoV), is a rare systemic illness involving persistent fever and extreme inflammation following exposure to SARS-CoV-2, the virus responsible for COVID-19.

Hydrogen peroxide can also be used as the oxidant. [2] Ph 2 S 2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour. Like most organic disulfides, the C–S–S–C core of Ph 2 S 2 is non-planar with a dihedral angle approaching 85°. [3] Ball-and-stick model of diphenyl disulfide.
[15] [18] [19] Overall, Children are associated with lower mortality rates than other age groups, when infected with COVID-19. [12] Some children who become infected develop a rare condition known as MIS-C, short for "multisystem inflammatory syndrome in children". [20] This causes a persistent fever and extreme inflammation.
A term for COVID-19 used by former United States president Donald Trump to emphasize that the pandemic started in China. Comirnaty. Main article: Comirnaty. The commercial name for the FDA approved COVID-19 vaccine from Pfizer, released August 21, 2021. It also has several other names or designators used on the actual vials. Community transmission
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]

Thioxanthone is a heterocyclic compound that is a sulfur analog of xanthone.. Thioxanthone can be prepared by the reaction of diphenyl sulfide with phosgene in the presence of catalytic aluminium chloride. [2]
