例えば、特定構造のビスホスファイト、典型的には以下に示すビスホスファイトA、ビスホスファイトB、ビスホスファイトCなどを用いた7-オクテン-1-アールのヒドロホルミル化反応において、直鎖状ジアルデヒド(1,9-ノナンジアール;以下NLと略称する)および分岐状ジアルデヒド(2-メチル-1,8-オクタンジアール;以下MOLと略称する)の生成比およびジアルデヒド選択率が開示されている(特許文献1参照)。
具体的には、ビスホスファイトAを用いる場合には、NL/MOL=85.1/14.9のジアルデヒドが選択率97.0%で、同一条件でビスホスファイトBを用いる場合には、NL/MOL=79.8/21.2のジアルデヒドが選択率97.0%で、同一条件でビスホスファイトCを用いる場合には、NL/MOL=79.7/20.3のジアルデヒドが選択率97.7%で得られることが示されている。

で示されるビスホスファイト(I)を、本発明の製造方法で用いるロジウム触媒を構成する成分として用いることが特徴である。
具体的には、別途調製したロジウム化合物溶液およびビスホスファイト(I)の溶液をそれぞれ反応器に導入する方法、いずれか一方の溶液を反応器に内在させ他方を固体として導入する方法、いずれか一方を固体として反応器に内在させ他方を溶液として導入する方法、両者を固体として反応器に内在させて溶媒を導入する方法、溶媒を反応器に内在させて両者を固体として導入する方法などが挙げられる。
