29 Acetals: Hal/X and O/O, S, Se, Te

DOI: 10.1055/sos-SD-029-00001

Warriner, S. L.Science of Synthesis, (2007291.

Volumes 29 and 30 of Science of Synthesis are jointly concerned with the synthesis of a class of functional groups that are characterized by the presence of exactly two heteroatoms singly bonded to a carbon atom, the classic feature of the acetal. Volume 29 deals primarily with acetals containing at least one oxygen or halogen atom while Science of Synthesis, Vol. 30 (Acetals: O/N, S/S, S/N, and N/N and Higher Heteroatom Analogues), deals with acetals of sulfur, nitrogen, and phosphorus (including O/N and O/P acetals). The product classes considered in Volume 29 are summarized in Table 1.
