A PdCl2(MeCN)2/PPhCy2 catalyst couples oxazoles with diarylmethyl carbonates or pivalates to form the corresponding triarylmethanes in good yields. The catalysis involves successive secondary benzylic sp3 C-O and heteroaromatic sp2 C-H cleavages and provides an effective access to heteroarene-containing triarylmethanes from nonhalogenated and nonmetalated starting materials, which is complementary to precedented cross-coupling technologies with organic halides and organometallic reagents.
