- In
organosulfur chemistry,
thioacetals are the
sulfur (thio-)
analogues of
acetals (R−CH(−OR)2).
There are two classes: the less-common monothioacetals...

nickel is used in
organic synthesis for desulfurization. For example,
thioacetals will be
reduced to
hydrocarbons in the last step of the
Mozingo reduction:...

aluminium chloride.
Thioacetals and
thioketals feature C−S−C−S−C bond sequence. They
represent a
subclass of sulfides. The
thioacetals are
useful in "umpolung"...

Examples include acetylenes (H−CC−R),
methyl sulfides (H−CH2SR),
thioacetals (H−CH(SR)2, e.g. dithiane),
methylphosphines (H−CH2PR2), furans, thiophenes...

influenced the
organosulfur chemistry by the
