"These two volumes are likely to become the new standard work in allene chemistry, and to maintain that position for a long time." (Angewandte Chemie I.E. und Angewandte Chemie)

"... overall, it was a pleasant experience to read the books. ... I certainly recommend this exciting and rounded opus to all researchers in the field of allene chemistry ... should not be missing as the new standard work of allenes in any good library collection. Chemists in academia and in industry will benefit from this opus." (Applied Organometallic Chemistry)
