The present invention provides a novel process for the preparation of 1,1-cyclopropanedimethanol cyclic sulfite which comprises: (a) contacting 1,1-cyclopropanedimethanol with dialkylsulfite in the presence of a base; and (b) removing from the reaction mixture the alcohol reaction by-product. This process is incorporated in the additional novel processes for preparing 1-(hydroxymethyl)cyclopropaneacetonitrile and 1-(thiomethyl)cyclopropaneacetic acid.
