さて、\documentclass{IEEEtran} で始まるものをコンパイルしようとしたのかしら?
ソースプログラムを見るとサポートしているのは book report letter article slides apa だけのようです。オプションを指定すると通らないケースも有るようです。
\documentclass[9pt]{article} .... 9pt なんて知らないと怒られます
その後の警告メッセージは preamble 部分で latex2rtf には想定外のものなのでしょう。
今回の検証は http://wfiot2018.iot.ieee.org/files/2017/07/IEEEtran_HOWTO.pdf
と https://okumuralab.org/tex/mod/forum/post.php?edit=15264
をちら見して作成したものです。コンパイルエラー原因が不明な場合は以下のソースに追加してエラーが出る状態にして質問されると良いと思います。
\documentclass[9pt,technote]{IEEEtran}
\usepackage[T1]{fontenc} % optional
\usepackage{amsmath}
\usepackage[cmintegrals]{newtxmath}
\begin{document}
\[
\frac{\pi}{2} =
\left( \int_{0}^{\infty} \frac{\sin x}{\sqrt{x}} dx \right)^2 =
\sum_{k=0}^{\infty} \frac{(2k)!}{2^{2k}(k!)^2} \frac{1}{2k+1} =
\prod_{k=1}^{\infty} \frac{4k^2}{4k^2 - 1}
\]
さんぷる

追伸 pandoc はとても便利なドキュメント変換アプリケーションです。インストール権限をお持ちなら導入されることをおすすめします。ちなみに pandoc もlatex を全て知っているか不明ですが少なくとも上記サンプルは通ります。またdocx 化したときは数式は削除されません。
