  A Rh(II)-catalyzed formal [3+3] cyclization of diazonaphthoquinones and propargyl alcohol is reported to afford 2,3-dihydro-1,4-benzodioxins. Various terminal propargyl alcohols react with diazonapthoquinone in the presence of Rh2(OAc)4 to give the corresponding dihydrodioxins in good to high yields. However, dihydrodioxins are not formed in the reaction of internal propargyl alcohols, and the O–H

  Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer having a hydroxyl and/or an aromatic ring functionality to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 .ANG. (as measured after water removal to a maximum of 5% by weight water), up to about 100 .ANG. and preferably in the range of about 10-45 .ANG., so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix. Alternatively, the intercalated complex can be exfoliated prior to or after combination with the organic liquid or the matrix polymer.

  通过将层状材料（例如云母石）与具有羟基和/或芳香环功能的插层单体接触，形成插层化合物，以吸附或插层插层单体在层状材料的相邻板层之间。足够的插层单体被吸附在相邻的板层之间，使相邻的板层扩展到至少约5 .ANG.的间距（在去除最多5％重量水后测量），最多可达约100 .ANG.，并且最好在约10-45 .ANG.的范围内，以便插层化合物可以轻松剥离成单独的板层。插层化合物可以与有机液体结合成粘稠的载体材料，用于输送载体材料或活性化合物；或将插层化合物与基质聚合物结合以形成强实心聚合物基质。或者，在与有机液体或基质聚合物结合之前或之后，可将插层化合物剥离。
