在30-40℃无溶剂条件下，在CO2 （1atm）和PhSiH3存在下，BPh3催化了N，N-二甲基苯胺或1-甲基吲哚的N-甲基化和C-甲基化（芳香环之间的亚甲基桥）。1-甲基-2-氧吲哚经1-甲基吲哚反应得到3,3 ' -亚甲基双（1-甲基吲哚）。
BPh3 catalyzed the N-methylation of secondary amines and the C-methylenation (methylene-bridge formation between aromatic rings) of N,N-dimethylanilines or 1-methylindoles in the presence of CO2 (1 atm) and PhSiH3 without solvent at 30–40 °C. A cascade reaction from 1-methyl-2-oxindole to 3,3′-methylenebis(1-methylindole) via 1-methylindole also proceeded.
