  In this article, we described 1/2-derivations of solvable Lie algebras with a
thread-like nilradical. Nontrivial transposed Poisson algebras with solvable
Lie algebras are constructed. That is, by using 1/2-derivations of Lie
algebras, we have established commutative associative multiplication to
construct a transposed Poisson algebra with an associated given Lie algebra.
