It is said that the Hartogs phenomenon occurs for the complex manifold \(X\) if any holomorphic map \(f:D\to X\) from the domain \(D\) over a Stein manifold extends holomorphically to \(f^*:D^*\to X\) where \(D^*\) is the envelope of holomorphy of \(D\). If \(X\) contains a rational curve, the Hartogs phenomenon can't occur for \((D=\mathbb{C}^ 2-(0,0))\). This is shown to be the only obstruction cohen \(X\) is holomorphically convex (S. Ivashkovich) and in this paper when: \(\dim_ \mathbb{C}(X)=3\), \(h^{2,0}(X)=0\) and \(X\) is bimeromorphic to a Kähler 3-fold (or in Fujiki's class \({\mathcal C})\). It is conjectured that the first two conditions should be unnecessary.
