How to make benzenecarbothialdehyde?
Just to clarify:
benzenecarbothialdehyde = benzaldehyde (where =O is replaced by =S)
But can I prepare this molecule by selective oxidation of benzyl mercaptan?
Any members who try to make one of this molecules or have access to the right articles?

See JACS, 110, 1976–1978 (DOI: 10.1021/ja00214a058) for its in situ synthesis and entrapment in the form of a Diels-Alder adduct.
The Lawesson's reagent is commonly used for the thionation of ketones. Other thiophosphorous reagents can sometimes be used instead and the
nucleophilic addition of H2S on the carbonyl group can also cause the thionation under certain conditions on certain carbonyl groups. But
unfortunatelly, aldehydes are not be so trivial due to the instability of thioaldehydes (thials) and/or non-isolability (see the JACS article).

…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)
