摘要：

Depending on the kind of R-1 and R-2, cyclic carbonates 1, in the presence of 10 mol% of Pd(PPh3)(4) and 10 equiv of paraformaldehyde, selectively undergo three types of reaction: 1 (R-1, R-2 not equal H) give dienes 3 exclusively; 1 (R-1 = R-2 = H and R-1 not equal H, R-2 = H) furnish 6-vinyl-1,3-dioxanes 5 exclusively, while 1 (R-1 = H, R-2 not equal H) give rise to 4-pentenyl formates 4 selectively (together with 3 as the minor products).
