Thanks so much! I was trying to get a bit more flexibility with that separate slide (e.g., have the title in the centre of the page and no toc). So I took inspiration from your great solution and defined a latex macro
#+begin_src latex \newcommand{\singleslide}[1]{{% \usebeamerfont{title} \begin{frame}[plain,c] \begin{center} \begin{minipage}[h]{.75\textwidth} \centering \textcolor{title}{\Large#1} \end{minipage} \end{center} \end{frame} }} #+end_src and a latex class #+begin_src emacs-lisp (add-to-list 'org-latex-classes '("my-org-beamer" "\\documentclass{beamer} ("\\singleside{%s}" . "\\singleslide{%s}"))))) #+end_src which did the job.
